A sample of the software:

A Projection Technique for Graph Bisection, contains fortran programs for graph bisection.
Linear Programming, contains matlab programs for linear programming, including a simplex method routine.
Semidefinite Programming, contains matlab programs for semidefinite programming, i.e. linear programs where the nonnegativity constraint is replaced by a positive semidefinite constraint on matrix variables. Also available: an annotated bibliography of SDP.
matrix completion problems with both the semidefinite and the Euclidean matrix completion problem.
Trust Region Subproblems consist in minimizing a quadratic function subject to a quadratic constraint.
