I will play with such organizations in other games to overcome my aversion to heuristic-friendly games . From April 21 to May 2, 2022, there was a programming contest on CodinGame. My initial objective for that contest was to pass legend and be in the top 100. They each get 1 base with 3 hit points (on opposed corners) and 3 heroes who can move, attack and use spells.

I foresaw that I will likely spend days validating my simulation and won't have time to use it for a search algorithm, provided I find a way to use a search for this game. November 2022 Prime Time Coding Challenge - Competitive Programming. For search-friendly games, you can get a good estimation of the improvement with the win rate of the new version versus the best to date version. The next two points, i.e. since the bot behavior is unpredictable, the win rates would be random. A tag already exists with the provided branch name. Those heroes can move around a large map to protect a base from spiders' attacks. crafting and combining conditions/scores, heavily depend on the testing capabilities. Submits took hours to complete, making testing ideas quite hard. CodinGame-Spring-Challenge-2022 My code for CG Spring Challenge 2022 Details can be read in my blog https://tzaph.blogspot.com/2022/05/my-experience-codingame-spring.html About My code for CG Spring Challenge 2022 Resources Readme Stars 0stars Watchers 1watching Forks A tag already exists with the provided branch name. Anybody interested in joining? However, wild mana collected by either the player or the opponent is unknown. Submits in the arena are so slow during a contest that you have to wait hours to assess the effect of a single change. First, collect data to consider for assigning goals to heroes. The teams start out at opposite corners of the map, near their base. I then run out of time to improve my bot to secure my place in the top 100 or reach an even better ranking. The 1 attacker version was intended to counter overaggressive bots and it would focus on controling the most monsters into the enemy base to get a quick win (it would also spam-control the lone defender (if any) away to let monsters do the job). This increased the difficulty for defenders without cooperation to farm wild-mana without losing a life. Some others went for 3 attackers, spamming CONTROL on the defender while pushing monsters in a reckless abandon trying to win faster than the other guy. If no monster was found, it would patrol the edge of the base, trying to farm mana without getting too far. Do you Know if haxe will be officialy supported soon ? I decided the submit the bot to the arena and it passed legend on Saturday, to my great amusement .

I also wanted to use some linreg to automatically change and determine weights but I lacked the Codingame API to do so, having to change the code by hand on every iteration wasnt feasible. Before the challenge, I grinded CodinGame to get a good grasp of what to expect during the challenge. My initial objective for that contest was to pass legend and be in the top 100. second, spiders that would eventually target my base if they maintain their direction, sorted by increased distance to my base. www.codingame.com. I ignored the FARM bot, as it was too much at an advantage with three heroes to farm wild mana and defend. I would define a number of attackers and defenders with some variables to remember the game state of previous turns (things like probable strategy of the enemy, how much defenders he has, how much he tries to CONTROL my heroes). Doing so generates mana, which is used to cast spells. AI . Online programming contest and hackathon " CodinGame Spring Challenge 2022". The Spring Challenge 2022 at CodinGame. Here are the simplified rules of the game, named Spider Attack. organizing the code such that it remains readable and extensible. The timeout given was very generous so there was no need to use a more optimised language, unless you were going for some search tree shenanigans. The yearly CodinGame Challenge started today. When I first saw the game rules, my objective became to pass legend OR be in the top 100 , as I knew that contest would be hard for me: There was a high probability that I would rage-quit this contest. codingcompetitions.withgoogle.com. 4CodinGame/SpringChallenge2022 issues, can help you solve programming problems. We were beaten by the University of Wroclaw, who proved to be formidable opponents throughout the challenge. Next, I wrote the code for the attacker, testing one idea at a time by measuring the win rates against the five bot versions. That meant that I could assign my idle hero to attack without weakening my defense. Based on that info, I would assign the attacker role to some of my heroes (theoretically I could end up with no attacker or no defender but I dont think such a case ever arose) and the defender role to the rest of them. cast a control spell on the spider to choose what will be its next velocity, preventing it from going toward a base and targetting it. My first time attending the spring challenges :tada::rocket:. 12.11 Sat 03:00 03:00. I used Python, of course. (i.e. Solve games, code AI bots, learn from your . CodinGameSpring Challenge 2022AI18,2883 CodinGame The Clash of Code section isn't a big of a deal since I'm used to speed-solve easy problems in CodeForces. CodinGame is a challenge-based training platform for programmers where you can play with the hottest programming topics. 10 days Kick Start Round H . I decided to write first an efficient defensive bot, that uses only two heroes (the last one remains idle). The program received data each turn describing the state of the battlefield and must output 3 lines, each one describing an heros action for the turn. Currently its at only 5% for Haxe. I ranked 264th out of 7695 players, thus reaching the middle of the pack in the Legends League. Two players controls a team of heroes. Prove your skills, win prizes, practice coding with other coders, have fun. Learn more. When I first saw the game rules, . Its a 10 day free bot programming competition with over 11.000 registered participants. I finally figured out a way to structure a heuristic bot that works for me. Spider Attack is the official name of the game used in the Spring Challenge 2022 Protect your base from monster attacks and outlive your opponent. If no spider is in range for the next two turns, I move the hero to a hardcoded position where it has an increased chance to spot spiders entering the map after being spawned or spiders that will soon target my base. This bot reached the gold league. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. I feel this is generally the case for heuristics-friendly games. Work fast with our official CLI. Since I consider competitive programming a way to improve professional programming, I did not want that to happen. The ranking system is already unstable, even more with a heuristic-friendly game. The two spiders are in the area of effect and are pushed 2200 units upward. defend, to handle spider threats while keeping an eye on what an attacker could do. Throughout the game monsters will appear regularly on the edges of the map. This contest was a very nice one. Pretty much everyone coded a routine to wind away large packs of monsters going towards the base, either as a last resort or to prevent a group WIND in the following turns. assess locally if a change in the code improved the bot. The challenge worked by leagues (namely Wood 2, Wood 1, Bronze, Silver, Gold and Legend) where you had to defeat a NPC Boss and a fixed amount of players to rank up. To do so, I sorted the list of visible spiders like so: I took the first three sorted spiders and assigned a hero to each of them. The defender routine had only one goal : keeping monsters away from the base. As always, I started with a short-sighted greedy heuristic algorithm control spiders toward the enemy base to increase the defense difficulty, control defenders outside of the base to give a higher chance to spiders to reach the opponent's base. Next, I analyze this data to assign each hero one of the following goals: Finally, for each assigned goal I use the allowed time to find the best way to implement it. https://www.codingame.com/contests/spring-challenge-2022/ Community starter AIs are . To measure the strength of the bot, I compute its win rate against five other bots I wrote: I improved my defense code until the bot largely beats the DEFEND bot. It was a lot of fun and many memorable battles (and bugs) were had. Not towards the enemy base but right behind the chosen attack spot, so that when they arrive into position, there would be a nice chunk of monsters already waiting to be yeeted into the base. Without testing, I would add bugged behaviors to the bot, such that it would become impossible to check if a change improves the bot: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Here is the main method of the bot: Nothing fancy yet: that function helps me to separate the code for defenders and the attacker while estimating how much time I could allocate to each hero. Writing the defense code required a lot of discipline as the weakness of my arena bot was clearly the attack. combine those conditions and scores to create a consistent behavior, e.g., sometimes an attacker is less of a threat than a shielded healthy spider near the central part of my base, but how to quantify it? There is a poll from 2019 in the CodinGame forum with Haxe on the list of requested languages. General Strategy. Instead, I thought to create multiple reference bots, using different strategies, and measure the performance of the tested version against all those bots. That's not a valid option during a time-limited event. It helped me with my difficulties to craft and combine conditions into a consistent behavior. This article gathers my feedback on the contest and the steps I followed to increase my ranking. Let's focus on the defense function to illustrate this organization. Bienvenue sur cette srie de live consacre au \"Spring Challenge 2022\", tournoi organis par http://codingame.com. The base visibility radius is 6000 space units, so an opponent could send spiders directly to the base center in one turn, without being seen. Other improvements include calculating 2 turns in advance for a quick setup, moving into position when possible rather than spending 10 mana winding a monster to the right place, going back to farming mode when mana was scarce and an utility to self-shield given the defender(s) history of controling or winding me out. If a hero is not attacking a spider that will target my base, and there is a spider in range, send that spider with a control spell toward the opponent's base. Codingame spring challenge 2022. If nothing happens, download GitHub Desktop and try again. I needed to find a way to organize my code before rewriting a complete bot and reaching the legend league. When a monster entered their reach, they would both spam WIND towards the enemy base to push it to the center so fast the enemy heroes couldnt react. So attacking the opponent seems a better tactic: Heroes can also be shielded, such that they won't be controlled or winded out by the opponent. TBC. Anybody interested in joining? From April 21 to May 2, 2022, there was a programming contest on CodinGame. first, spiders that are targetting my base, sorted by increased distance to my base. On Legends there was no Boss and players where ranked with an ELO-like system. Whenever a spider is inside a player base, it will target that base. Each sub-method is composed of three steps. As of Tuesday 1 November 2022, take a stock on the news in Paris and its surroundings, the latest . I would first patrol the map for a given number of rounds (or until I spotted the enemy making a move) trying to maximize mana farming by putting my heroes where they could hit the most monsters at once. The challenge is still available as a bot battle minigame so I wont disclose any code here but Ill speak about strategy. Having a code organization and a way to test a bot locally, it was time to design a better bot to reach the legend league. Effects of casting a wind spell in the up direction. I decided that the attacker code would be ready if the win rates against all five bot versions were above 90%. Spring Challenge 2022. However, this organization helped me to overcome the code mess I usually produce when working with heuristics. There are many ideas I have not tested or improvements I have not done. CodinGame is a challenge-based training platform for programmers where you can play with the hottest programming topics. Here the answer is so unpredictable that every new riddle is like a leap into the unknown where the world is turned upside down and unbelievable things become possible. Spiders move from four spawning points outside the game map, with initial random direction, and initial health increasing over time. A hero can prevent a spider from attacking a base with different actions: With three heroes in defense, it's very unlikely to lose a life. It's so much simpler when you have the actual referee code. I had a lot of specific little tweaks for defense : if one or more attacker is nearby and the defender is alone (or far from the other), weight very heavily the self-shield because a single CONTROL could spell (get it ?) I took care of that point by casting wind on spiders just before they entered my base. When I code heuristics, it quickly becomes an unmaintainable spaghetti plate. Each sub-method takes available mana as a parameter and returns how much mana is available for subsequent steps. I may need to investigate how to make a referee compatible with brutaltester myself. My slowness is less noticeable when I write search algorithms: As my heroes followed spiders toward my base, they did not farm wild mana. The first step could collect all recently seen opponents near my base, compute the future positions of spiders near my base, store the date at which a spider will leave the map or reach my base center, and collect all my available defenders (not controlled at the current turn).
