英文文献摘要：
Mixed-Integer optimization represents a powerful tool for modelling many optimization problems arising from real-world applications. The Feasibility pump is a heuristic for finding feasible solutions to mixedinteger linear problems. In this work, we propose a new feasibility pump approach for MIP problems using concave non differentiable penalty functions for measuring solution integrality.
