Model mixed integer linear programs in an algebraic way directly in R. The model is solver-independent and thus offers the possibility to solve a model with different solvers. It currently only supports linear constraints and objective functions. See the 'ompr' website < https://dirkschumacher.github.io/ompr> for more information, documentation and examples.
omprnow uses sparse constraint matrices.
extract_constraintsnow returns a sparse matrix and
objective_functionreturns a sparse vector.
