    <h1 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">为何</span>写这篇<span style="color: black;">文案</span></h1>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">写此篇<span style="color: black;">文案</span><span style="color: black;">重点</span>有以下几点考量。其一,传统游戏AI基于规则实现,有的<span style="color: black;">运用</span>状态机、有的<span style="color: black;">运用</span><span style="color: black;">行径</span>树、<span style="color: black;">乃至</span>有些运用搜索算法来寻找最优的动作,策略游戏<span style="color: black;">常常</span>综合运用多种技术,有<span style="color: black;">必定</span>的<span style="color: black;">科研</span>价值;其二,尽管基于规则的传统AI没法和人类对抗,但它<span style="color: black;">触及</span>的程序抽象思想值得<span style="color: black;">科研</span>;其三,我之前写过几个AI<span style="color: black;">关联</span>的材料,一个是课程《各类型游戏人工智能算法》,它<span style="color: black;">重点</span>偏重于<span style="color: black;">区别</span>类型游戏AI的综述,另一个课程 《直观理解AI博弈原理》<span style="color: black;">重点</span>介绍象棋、围棋、王者荣耀的AI实现,更偏重于强化学习<span style="color: black;">办法</span>的演进,两者中间还缺乏一个综合实例,而星际争霸<span style="color: black;">设备</span>人UAlbertaBot刚好<span style="color: black;">能够</span>填补这一空白。本文<span style="color: black;">重点</span>参考UAlbertaBot的源码、Wiki,以及<span style="color: black;">关联</span>的几篇论文,<span style="color: black;">咱们</span>并不去关心程序<span style="color: black;">怎么样</span>安装和运行,而是关注它的设计和原理。</span></p>
    <h1 style="color: black; text-align: left; margin-bottom: 10px;">UAlbertaBot是什么</h1>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">UAlbertaBot是一套开源的星际争霸AI,该程序自2010年<span style="color: black;">起始</span>参加<span style="color: black;">各样</span>星际AI的比赛,并且赢得2013年AIIDE星际争霸AI比赛的冠军。它的作者是David Churchill,纽芬兰纪念大学的计算机助理教授。UAlbertaBot的开源<span style="color: black;">位置</span>如下:</span></p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">在2018年以前,<span style="color: black;">运用</span>强化学习<span style="color: black;">办法</span>的AI尚未成熟,UAlbertaBot等星际争霸<span style="color: black;">设备</span>人<span style="color: black;">作为</span>游戏AI竞技的<span style="color: black;">表率</span>。尽管在2018年以后强化学习AI展现出很强的能力,但强化学习AI训练难度大且难以用<span style="color: black;">规律</span><span style="color: black;">暗示</span>它的<span style="color: black;">行径</span>,游戏产业依然广泛的<span style="color: black;">运用</span>传统AI。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">文案</span>会分如下几篇</span></p><span style="color: black;">架构和规则,宏观介绍UAlbertaBot的原理</span><span style="color: black;">建造<span style="color: black;">次序</span>搜索,介绍<span style="color: black;">运用</span>深度搜索算法去找到最优建造<span style="color: black;">次序</span>的<span style="color: black;">办法</span></span><span style="color: black;">战斗模拟<span style="color: black;">评定</span>,介绍模拟队伍作战<span style="color: black;">评定</span>能否获胜的<span style="color: black;">办法</span></span><span style="color: black;">starterbot,一个最简单的<span style="color: black;">设备</span>人,从中理解最<span style="color: black;">基本</span>星际AI的写法</span><span style="color: black;">策略制定,策略制定部分的代码分析</span><span style="color: black;">建造实现,生产、建造<span style="color: black;">关联</span>系统的代码分析</span><span style="color: black;">战斗实现,战斗<span style="color: black;">关联</span>代码分析</span><span style="color: black;">寻路算法,地图<span style="color: black;">关联</span>代码的分析</span>
