This chapter presents the primal heuristics in the feasibility pump family. The fundamental idea of all feasibility pump algorithms is to construct two sequences of points that hopefully converge to a feasible solution of a given optimization problem. The points in the first sequence are feasible with respect to the linear programming constraints of the MIP, while those in the second sequence respect the integrality requirements. This basic concept has been developed in many ways in the literature, and this chapter gives an exhaustive overview of the resulting algorithms.
