An Integrated CP/OR Method for Optimal Control of Modular Hybrid Systems [PDF]
, 2014 This paper concerns the optimal control of modular hybrid systems synchronized by shared variables. Instead of synchronizing the discrete dynamics of the system into one global mode before optimization, Constraint Programming (CP) is used to model the ...

Non-convex mixed-integer nonlinear programming: A survey
Surveys in Operations Research and Management Science, 2012 Abstract A wide range of problems arising in practical applications can be formulated as Mixed-Integer Nonlinear Programs (MINLPs). For the case in which the objective and constraint functions are convex, some quite effective exact and heuristic algorithms are available.

A Status Report on Conflict Analysis in Mixed Integer Nonlinear Programming
, 2019 Mixed integer nonlinear programs (MINLPs) are arguably among the hardest optimization problems, with a wide range of applications. MINLP solvers that are based on linear relaxations and spatial branching work similar as mixed integer programming (MIP ...
