WebThe Reformulation-Linearization-Technique (RLT) is a method that generates such tight linear pro-gramming relaxations for not only constructing exact solution algorithms, but also to design powerful heuristic procedures for large classes of discrete combinatorial and continuous nonconvex programming Webreformulation of an objective function in terms of its epigraph, etcetera. The result of such reformulations is that the algorithm to be devised will yield diﬀerent types of approximations of the original problem (such as outer approximations of constraints and/or the epigraph of the objective function), and also
