BFOUR: A Fortran Subroutine for
T. Lehmann, K. Schittkowski, Report, Department of Computer Science, University of Bayreuth (2015)
The Fortran subroutine BFOUR is an implementation of a branch and bound algorithm for mixed-integer optimization. BFOUR is applied to solve mixed-integer quadratic programs as part of the code MIQL, and to solve mixed integer nonlinear optimization problems in combination with the code MISQP. The usage is documented and numerical results are presented for MIQL.
