WebbBased on personal experience, I'd say that simplex methods are marginally easier to understand how to implement than interior point methods, based on personal experience from implementing both primal simplex and a basic interior point method in MATLAB as part of taking a linear programming class. Webbsimplex criterion rule -of linear programming and the term C B B 1a - c , is called the reduced cost. If there are no variables with negative values of C B B-1a - c , then the solution cannot be improved on and is optimal. However, if a variable is identified by this rule then it should be entered into the basis.

WebbLinear programming is an optimization technique for a system of linear constraints and a linear objective function. An objective function defines the quantity to be optimized, and the goal of linear programming is to find the values of the variables that maximize or minimize the objective function.
