Unlike divide and conquer, it computes the sub-problems iteratively and stores the solutions for future use. Finally, we combine the solutions of the sub-problems to achieve the solution of the main problem: 6. Divide and Conquer vs Dynamic Programming Now we know the theoretical idea behind ...
When Istarted to learn algorithmsit was hard for me to understand the main idea of dynamic programming (**DP**) and how it is different from divide-and-conquer (**DC**) approach. When it gets to comparing those two paradigms usually Fibonacci function comes to the rescue as great example...
动态规划三大重要概念:最优子结构,边界,状态转移公式(问题规模降低,如问题由 n 的规模降低为 n−1 或 n−2 及二者之间的关系);0. 爬台阶F(n)⇒F(n−1)+F(n−2)F(n−1),F(n−2) 即是 F(n) 的最优子问题;F(1)=1,F(2)=2...

Divide and Conquer should be used whensame subproblems are not evaluated many times. Otherwise Dynamic Programming or Memoization should be used. For example, Quicksort is a Divide and Conquer algorithm, we never evaluate the same subproblems again. On the other hand, for calculating nth Fibonacci...
Divide and Conquer approach: fib(n) If n < 2, return 1 Else , return f(n - 1) + f(n -2) Dynamic approach: mem = [] fib(n) If n in mem: return mem[n] else, If n < 2, f = 1 else , f = f(n - 1) + f(n -2) ...
