"Description": "Model mixed integer linear programs in an algebraic way\ndirectly in R. The model is solver-independent and thus offers\nthe possibility to solve a model with different solvers. It\ncurrently only supports linear constraints and objective\nfunctions. See the 'ompr' website\n for more information,\ndocumentation and examples.",
