Greedy-choice property: global 的最佳化可由 local 的最佳化來得到(也是 greedy method 和 DP 不同之處) ? Optimal substructure: 大問題的最佳解包含將 大問題切開後之小問題的最佳解 3 Problem: Knapsack problem ? 給 n 個物體,每個物體的重量 wi 以及價值 vi, 背包的容量 C ? 選擇一些物體放入背包中...

First, we will see how we can solve this problem using a min-heap (priority queue) if the activities given are in random order. After that, we will see an optimized method to solve this question without using a priority queue. One very important question is why we should always consider...
We prefer the first method.The next step of our modification is a reduction of factors of a strong product. For each i \in \{1,2,\ldots ,r\} and any u,v \in V(G_i), if N_{G_i}[u] \subseteq N_{G_i}[v], then ...
(a) Schematic diagram of grid method (b) Paths generated by different distance functions. Full size image The two marking modes can be transformed into each other and their correspondence is $$ N = x + n \times y $$ (1) $$ \left\{ {\begin{array}{*{20}c} {x_{i} = [(N_...
Since the method enables the users to specify parameters according to their preference, it is much more flexible than the previous methods. Another merit of this framework is that it is easy to expand by adding new constraints into the existing framework. 3 Feature based video summarization ...
