Textbook Question
Chapter 14, Problem 10P
The grid search is another brute force approach to optimization. The two-dimensional version is depicted in Fig. P14.10. The x and y dimensions are divided into increments to create a grid. The function is then evaluated at each node of the grid. The denser the grid, the more likely it would be to locate the optimum.
Develop a program using a programming or macro language to implement the grid search method. Design the program so that it is expressly designed to locate a maximum. Test it with the same problem as Example 14.1.
