Graph layout methodologies often solve difficult subproblems in order to satisfy the aesthetic constraints: finding the maximal planar subgraph, minimizing crossings, minimizing area, maximizing symmetries, etc. One standard approach is to translate the subproblem into a linear optimization problem (LOP) and to use a standard mathematical tool to find the solution. The standard solving tool for such LOPs is ILOG CPLEX. ILOG CPLEX delivers high-performance, robust, flexible optimizers for solving linear, mixed-integer and quadratic programming problems (including mixed integer quadratic constrained problems). It is a component that includes C, C++ and Java API, and it is integrated via the Concert Technology into the ILOG Optimization Suite. With ILOG JViews, we also offer a visualization suite that includes sophisticated graph layout algorithms. Our recent investigations focused on cross-product development and the question, how ILOG CPLEX can be used to help graph layout and how ILOG JViews can be used to help the LOP solving.
