Abstract: Integer programming deals with optimization problems with decision variables being all integer or partly integer. Integer programming has been one of the most active research directions in optimization due to its wide applications in operations research and management science. In this survey paper, we first briefly review the background of integer programming and summarize the fundamental results of linear and nonlinear integer programming. We then focus on some recent progress in several research topics, including semi-definite programming relaxation and randomized methods for 0-1 quadratic programs, optimization problems with cardinality and semi-continuous variables, and co-positive cone program representations and approximations of 0-1 quadratic programs. Finally, we indicate some research perspectives and open problems in integer programming.

Key words: integer programming, 0-1 quadratic programming, positive semi-definite programming (SDP) method, semicontinuous variables and cardinality constraint, copositive cone program, hierarchies of SDP approximation to copositive cone
