Coopr: a COmmon Optimization Python Repository The Coopr software project integrates a variety of Python optimization-related packages. Coopr supports a diverse set of optimization capabilities that can be used formulate and analyze optimization applications: Pyomo: Formulate algebraic models within Python’s modern programming language PySP: Generic solvers for stochastic programming problems COLIN: Scripts that simplify IO between optimizers and black-box applications SUCASA: Customize MIP solvers to expose model structure to the MIP solver engine
