A simple example of what Integer Linear Programming can do

WebAccording to the Mixed-Integer Linear Programming Definition , there are matrices A and Aeq and corresponding vectors b and beq that encode a set of linear inequalities and linear equalities A · x ≤ b A e q · x = b e q. These linear constraints restrict the solution x. Webexample x = intlinprog (f,intcon,A,b) solves min f'*x such that the components of x in intcon are integers, and A*x ≤ b. x = intlinprog (f,intcon,A,b,Aeq,beq) solves the problem above while additionally satisfying the equality constraints Aeq*x = beq. Set A = [] and b = [] if no inequalities exist. example crystal\u0027s 1t
