Abstract:

• In the article we translate the camera layout problem into the vertex cover P n equ1 problem in graph theory. • We first proved two important inequalities on the problem to show the main result. • We designed an approximation algorithm to solve the vertex cover P 3 equ2 problem. • We proved the performance factor of the algorithm is no more than 2.
