second, spiders that would eventually target my base if they maintain their direction, sorted by increased distance to my base. by casting a wind on a healthy spider toward my base), try to cancel the wind effect while throwing the attacker out of my base. 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. However, this organization helped me to overcome the code mess I usually produce when working with heuristics. L'objectif est de dvelopper un programme . No, I dont know anything new. 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. www.codingame.com. Also, the given referee on GitHub is in java, and I have not practiced that language since my engineering school days, I neved used the referee locally. I felt ashamed I never tried to do it before. The game mechanics are interesting. SHIELD would render the target immune to spells for 12 rounds, WIND would push all entities around the caster towards a single point, CONTROL would force the target to move towards a single point for 1 round (if the target was a monster and that monster wasnt already targeting a base, it would then continue in the given direction). --- Join the CodinGame. The ranking system is already unstable, even more with a heuristic-friendly game. Having a heuristic-friendly game is not a bad idea as it seems easier for beginners or non-professional developers. I decided to write first an efficient defensive bot, that uses only two heroes (the last one remains idle). Overall Im pretty happy with the results for my first codingame challenge ever ! It's a two-player game where each player controls three heroes. If I had enough mana, I also would CONTROl far away monsters that would at one point come in range of the base and divert them to either the center of the enemy base or my own wind cannon starting point. The attacker routine on the other hand had a lot of different parameters. Rated. November 2022 Prime Time Coding Challenge - Competitive Programming. cast a shield spell on spiders directed toward the enemy base, such that they are insensitive to wind and control for 12 turns. My initial objective for that contest was to pass legend and be in the top 100. Spring Challenge 2022 Heuristics on Spider Attack Posted by Tom Delame on May 14, 2022 .

Spiders move from four spawning points outside the game map, with initial random direction, and initial health increasing over time. le-de-France is densely populated and . I mostly focused on search algorithms before that contest, so tuning and evaluating heuristics remained quite obscure to me. Join our next contest for free now! I tried to code an attacker, but I did not have enough free time to work on the contest anymore. Monsters within a certain radius of a players base will be attracted to it, and if they are not killed before reaching it they do 1 hit point of damage. I used a greedy algorithm to defend, a simple trick to increase the wild-mana farmed, and a stationary attacker. If the spider reaches the central part of a base, the corresponding player loses one life. 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.

The next two points, i.e. Decreasing the number of matches per submission is not the solution. 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. 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. https://www.codingame.com/contests/spring-challenge-2022/ Community starter AIs are . A meta quickly emerged : 1 hero would patrol the base and defend it for the whole game. 12.11 Sat 00:00 24:00. If no monster was found, it would patrol the edge of the base, trying to farm mana without getting too far. TBC If nothing happens, download GitHub Desktop and try again. Rank: Unknown Language: Typescript (transpiled to JS). craft conditions and scores with numbers, e.g., what are the criteria to decide an attacker is a threat to our defense and should be removed? This led to very interesting strategies : some people shielded monsters in their own base to prevent them from being WINDed in and get enough time to kill them by attacking normally. So I started to code a simulation that would serve for validation and maybe a search algorithm in C++. Bienvenue sur cette srie de live consacre au \"Spring Challenge 2022\", tournoi organis par http://codingame.com. I managed to remain in the top 100 up to Monday morning, but my bot did not perform well in the general resubmission.

The challenge pits two players against each other on a rectangular map. TBC. Throughout the game monsters will appear regularly on the edges of the map. 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. I will focus on producing better bots faster. Codingame has a new challenge this Spring, and we talk about the rules and strategies that can be applied to make an AI bot.Codingame. The principle was the same : for a given hero, get all of his possible actions, weight them against the game state and execute the best scoring course of action. 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 ?) 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. In this contest, I could not find any trivial way to ensure a bot improved. codingcompetitions.withgoogle.com. We can see that having a hero (in blue) guarding my base because an attacker (in red) has been spotted helped me to keep my three lives. Bot for the CodinGame 2022 Spring Challenge.

After a while (or a certain amount of mana was reached), they would both go towards an edge of the enemy base and stand there. However, this requires a much faster submission. 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). Effects of casting a wind spell in the up direction. I then run out of time to improve my bot to secure my place in the top 100 or reach an even better ranking. Currently its at only 5% for Haxe. first, spiders that are targetting my base, sorted by increased distance to my base. Contribute to de-passage/spring-challenge-2022 development by creating an account on GitHub. The Optimization section is a bit hard for me as heuristics related . They are multiple strategies to win and it's possible to switch from different strategies depending on the context (remaining life, attacker spotted, large mana amount, etc). The game has a fog of war: a player can see spiders and the opponent's heroes only around the base or around its heroes. Anybody interested in joining? farm, deal damage to spiders to increase wild mana. Codingame spring challenge 2022. 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. The 2 attackers version implemented the infamous wind cannon with some tweaks. RTSMOBA*1. I used Python, of course. It's a 10 day free bot programming competition with over 11.000 registered participants. My initial objective for that contest was to pass legend and be in the top 100. Each sub-method takes available mana as a parameter and returns how much mana is available for subsequent steps. Once the spider's health reaches zero, the spider is killed and removed from the game. From April 21 to May 2, 2022, there was a programming contest on CodinGame. I decided to ignore such wind canons, as I thought it won't be necessary to reach the legend league.

There was however an overpowered mechanic: wind spells are stacked. Contribute to fatmage/CodinGame-Spring-Challenge-2022 development by creating an account on GitHub. Since I consider competitive programming a way to improve professional programming, I did not want that to happen. When all three heroes of the same player cast wind spell in the same area, affected entities are pushed away for 6600 space units. I enjoy this organization as I find it easier to add considerations, tweak the goal assignment, or test new tactics to implement assigned goals. cast a wind spell such that the spider is expelled further from the base, when the spider is thrown far away from the base, it won't target it anymore but instead chose a random direction. (i.e. It was a lot of fun and many memorable battles (and bugs) were had. Online programming contest and hackathon " CodinGame Spring Challenge 2022". The situation would be worse with fewer matches to measure a bot performance. 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. 00:00 - Analyse de l'nonc et implmentation simple 08:30 - Implmentation avec un Comparator et Collections.sort 24:30. They then each had a generic routine (one for defense, one for offense). Submits took hours to complete, making testing ideas quite hard. Now, spiders are almost always outside of my base, so I naturally farm wild-mana with the same algorithm. Second, analyze that data to produce goal assignments for each available hero. 10 days Kick Start Round H . get closer to a spider such that the hero can hit it, for each hit point, the spider's health decreases, and the player's mana increases.
