WebA linear program can take many di erent forms. First, we have a minimization or a maximization problem depending on whether the objective function is to be minimized or maximized. The constraints can either be inequalities ( or ) or equalities. WebBasic Concepts In a general integer programming or integer linear programming problem, we seek to minimize a linear cost function over all n -dimensional vectors x subject to a set of linear equality and inequality constraints as well as integrality restrictions on some or all of the variables in x. min c T x s.t. A x = b x ≥ 0 x ∈ Z n
