A feasibility pump heuristic for general mixed-integer problems
Finding a feasible solution of a given Mixed-Integer Programming (MIP) model is a very important (NP-complete) problem that can be extremely hard in practice. Very recently, Fisch...

Design of high-performance CMOS charge pumps in phase-locked loops
Practical considerations in the design of CMOS charge pumps are discussed. The non-ideal effects of the charge pump by the leakage current, the mismatch, and the delay offset in t...

Repairing MIP infeasibility through local branching
Finding a feasible solution to a generic Mixed-Integer Program (MIP) is often a very difficult task. Recently, two heuristic approaches called Feasibility Pump and Local Branching...
