Mixed Integer Programming versus Evolutionary Computation for Optimizing a Hard Real-World Staff Assignment ProblemAssigning staff to engagements according to hard constraints while optimizing several objectives is a task encountered by many companies on a regular basis. Simplified versions of such assignment...

107 A Brief History of Linear and Mixed-Integer Programming Computation For many of us, modern-day linear programming (LP) started with the work of George Dantzig in 1947. However, it must be said that many other scientists have also made seminal contributions to the subject, and some would...

In the history of integer programming, the basic branch-and-bound method has been extended to the so-called branch-and-cut (B&C) method. This means that, besides branching, additional valid inequalities or cuts are introduced at the nodes of the branch-and-bound tree to tighten the formulatio...

Such McCormick relaxations provide lower bounds, for example, in branch-and-bound procedures for mixed-integer nonlinear programs but have not gained much attention in PDE-constrained optimization so far. This lack of attention may be due to the distributed nature of such problems, which on the ...
