This paper concludes five years of AI competitions based on Legends of Code and Magic (LOCM), a small Collectible Card Game (CCG), designed with the goal of supporting research and algorithm development. The game was used in a number of events, including Community Contests on the CodinGame platform, and Strategy Card Game AI Competition at the IEEE Congress on Evolutionary Computation and IEEE Conference on Games. LOCM has been used in a number of publications related to areas such as game tree search algorithms, neural networks, evaluation functions, and CCG deckbuilding. We present the rules of the game, the history of organized competitions, and a listing of the participant and their approaches, as well as some general advice on organizing AI competitions for the research community. Although the COG 2022 edition was announced to be the last one, the game remains available and can be played using an online leaderboard arena.

翻译：本文总结了五年来基于《魔法与代码传说》（Legends of Code and Magic, LOCM）的AI竞赛历程。LOCM是一款小型集换式卡牌游戏（Collectible Card Game, CCG），其设计初衷是支持算法研究与开发。该游戏被应用于多项赛事，包括CodinGame平台上的社区竞赛，以及IEEE进化计算大会和IEEE游戏会议举办的策略卡牌游戏AI竞赛。LOCM已被多篇论文采用，涉及博弈树搜索算法、神经网络、评估函数及CCG卡组构筑等领域。本文介绍了游戏规则、有组织的竞赛历史、参赛者及其方法的清单，同时为研究界组织AI竞赛提供了一般性建议。尽管COG 2022届竞赛被宣布为最后一届，但该游戏仍可访问，并可通过在线排行榜竞技场进行对战。
