#include "OsiClpSolverInterface.hpp" int main() { OsiClpSolverInterface solver; solver.readMps("example.lp"); solver.initialSolve(); double objValue = solver.getObjValue(); // do something with objValue return 0; }In this example, we create an instance of the OsiClpSolverInterface class and read in an LP from a file using the `readMps` method. We then solve the LP using the `initialSolve` method and retrieve the objective value using the `getObjValue` method. The package library for OsiSolverInterface is COIN-OR (Computational Infrastructure for Operations Research), which is a collection of open-source software tools for optimization and related areas.
