<h1 id="122">12.2 分治搜索策略<a class="headerlink" href="#122" title="Permanent link">¶</a></h1>
|
2023-08-27 23:41:10 +08:00
|
|
|
|
<p>我们已经学过，搜索算法分为两大类。</p>
|
2023-07-24 03:03:58 +08:00
|
|
|
|
<ul>
|
|
|
|
|
|
<li><strong>暴力搜索</strong>：它通过遍历数据结构实现，时间复杂度为 <span class="arithmatex">\(O(n)\)</span> 。</li>
|
2023-12-02 06:24:11 +08:00
|
|
|
|
<li><strong>自适应搜索</strong>：它利用特有的数据组织形式或先验信息，时间复杂度可达到 <span class="arithmatex">\(O(\log n)\)</span> 甚至 <span class="arithmatex">\(O(1)\)</span> 。</li>
|
2023-07-24 03:03:58 +08:00
|
|
|
|
</ul>
|
2023-12-02 06:24:11 +08:00
|
|
|
|
<p>实际上，<strong>时间复杂度为 <span class="arithmatex">\(O(\log n)\)</span> 的搜索算法通常是基于分治策略实现的</strong>，例如二分查找和树。</p>
|
2023-07-17 04:21:02 +08:00
|
|
|
|
<ul>
|
|
|
|
|
|
<li>二分查找的每一步都将问题（在数组中搜索目标元素）分解为一个小问题（在数组的一半中搜索目标元素），这个过程一直持续到数组为空或找到目标元素为止。</li>
|
2023-12-02 06:24:11 +08:00
|
|
|
|
<li>树是分治思想的代表，在二叉搜索树、AVL 树、堆等数据结构中，各种操作的时间复杂度皆为 <span class="arithmatex">\(O(\log n)\)</span> 。</li>
|
2023-07-17 04:21:02 +08:00
|
|
|
|
</ul>
|
2023-08-27 23:41:10 +08:00
|
|
|
|
<p>二分查找的分治策略如下所示。</p>
|
2023-07-17 04:21:02 +08:00
|
|
|
|
<ul>
|
2023-12-02 06:24:11 +08:00
|
|
|
|
<li><strong>问题可以分解</strong>：二分查找递归地将原问题（在数组中进行查找）分解为子问题（在数组的一半中进行查找），这是通过比较中间元素和目标元素来实现的。</li>
|
|
|
|
|
|
<li><strong>子问题是独立的</strong>：在二分查找中，每轮只处理一个子问题，它不受其他子问题的影响。</li>
|
2023-08-20 14:52:42 +08:00
|
|
|
|
<li><strong>子问题的解无须合并</strong>：二分查找旨在查找一个特定元素，因此不需要将子问题的解进行合并。当子问题得到解决时，原问题也会同时得到解决。</li>
|
2023-07-17 04:21:02 +08:00
|
|
|
|
</ul>
|
2023-07-24 03:03:58 +08:00
|
|
|
|
<p>分治能够提升搜索效率，本质上是因为暴力搜索每轮只能排除一个选项，<strong>而分治搜索每轮可以排除一半选项</strong>。</p>
|
2023-12-02 06:24:11 +08:00

<h3 id="1">1. 基于分治实现二分查找<a class="headerlink" href="#1" title="Permanent link">¶</a></h3>
|
2023-07-24 03:03:58 +08:00
|
|
|
|
<p>在之前的章节中，二分查找是基于递推（迭代）实现的。现在我们基于分治（递归）来实现它。</p>
