I will give 4.
(1) Linear Programming (LP)- LP is a method used to optimize linear objective functions subject to linear constraints.
(2)Integer Programming (IP) - IP extends linear programming to problems where some or all decision variables must take integer values.
(3)Dynamic Programming (DP)- DP is used to solve problems that can be broken down into smaller subproblems.
(4)Network Analysis - Network analysis methods, such as Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT), are used for project scheduling and management.
