《Head First 设计模式》C++实现【策略模式(Strategy Pattern)】
摘要 《Head First 设计模式》书中第2章——策略模式(Strategy Pattern)的C++代码实现。策略模式(Strategy Pattern)：定义了算法簇，分别封装起来，让他们之间可以相互替换，此模式让算法的变化独立于使用算法的客户。 实现代码 //《Head First 设计模 ......
ABC320G Slot Strategy 2 (Hard)
ABC320G 直接做不是很好做，考虑用二分将其转化为判断可行性的问题。 发现每个字符串都会对应一个唯一的时间，每个时间最多也只对应一个字符串，这启发我们将字符串与时间连边，然后跑二分图的最大匹配。这样的总点数是 \(\mathcal{O}(nm)\) 的，无法通过。但是每一种字符中只有前 \(n\ ......
策略模式(Strategy Pattern) .Net Core实现
在策略模式（Strategy Pattern）中，一个类的行为或其算法可以在运行时更改。这种类型的设计模式属于行为型模式。 在策略模式中，我们创建表示各种策略的对象和一个行为随着策略对象改变而改变的 context 对象。策略对象改变 context 对象的执行算法。 意图：定义一系列的算法,把它们 ......
策略模式 Strategy
一、定义 定义了算法家族，分别封装起来，让它们之间可以相互替换 此模式让算法的变化不会影响到使用算法的用户 二、适用场景 系统有很多类，而它们的区别仅仅在于行为不同 一个系统需要动态的在几种算法中选择一种 三、优缺点 1、优点 符合开闭原则 OpenClose 避免使用多重条件转移语句switch ......

什么是 Two-Tier ERP strategy
当一家公司为组织的不同部分实施不同的 ERP 系统时，行业将这种策略称为二层 ERP 策略。这种策略是由对大型复杂组织的需求与小型简单组织的需求非常不同的认识驱动的。通常作为子公司的较小组织，如果运行符合其需求的 ERP 解决方案，而不被其较大的姐妹组织所需的过度复杂的解决方案所困扰，可以更有效。随 ......
