​ QSeek is a local search solver designed for general mixed-integer quadratic programming (MIQP) problems, capable of handling cases where quadratic terms appear in the objective function, constraints, or both. It is the updated version of LS-IQCQP. Unlike its predecessor, LS-IQCQP, which primarily solves integer quadratic programming (IQP) problems, QSeek extends its capabilities to solve not only integer problems but also mixed-integer problems.

• To use QSeek, run ./QSeek cutoff_time(second) filename.lp.
