1. Overview algorithm (algorithm) is an accurate and complete description of the solution to the problem. It is a series of clear instructions for solving the problem. The algorithm represents a system method to describe the policy mechanism for solving the problem. The advantages and disadvantages of an algorithm can be measured by space complexity and time complexity. 2. A feature algorithm should have five important features: poor, definite, input, output, and feasibility. 3 element 1: calculation and operation of Data Objects: 2. control structure of the algorithm: 4. Evaluation of 4.1 time complexity 4.2 space complexity 4.3 correctness 4.3 readability 4.3 robustness 5: method 5.1 progressive method 5.2 Recursive Method 5.3 exhaustive method 5.4 greedy algorithm 5.5 division and Control Method 5.6 Dynamic Programming Method 5.7 iterative method 5.8 branch boundary method 5.9 Backtracking Method
