# Summary

Algorithm design techniques are very important in order to formulate, understand, and develop an optimal solution to a complex problem. In this chapter, we have discussed algorithm design techniques, which are very important in the field of computer science. Important categories of algorithm design, such as dynamic programming, greedy approach, and divide and conquer, we discussed in detail along with implementations of important algorithms.

The dynamic programming and divide-and-conquer techniques are quite similar in the sense that both solve a bigger problem by combining the solutions of the sub-problems. Here, the divide-and-conquer technique partitions the problem into disjointed sub-problems, solving them recursively, and then combines the solutions of the sub-problems to obtain the solution of the original problem, whereas, in dynamic programming, this technique is employed when sub-problems overlap, and recomputation of the same sub-problem is avoided.
