Dear CBC team,<br>we successfully use CBC (2.7.7) for AMPL models via OSAmplClient from AMPL translator.<br>But now, to "distribute" the computational load, we need to run CBC application on one server, but perform analysis of solution in AMPL translator running on another server.<br>
The most convenient would be if CBC-solution will be returned in AMPL format (*.sol file created by write_sol ASL routine). <br>But not in CBC nor in OSSolverService I can not find an option (similar to "wantsol" for AMPL-solvers) telling to write solution in AMPL format. <br>
At the same time in CbcSolver.cpp I see a call of writeAmpl(...) procedure, defined in Cbc_ampl on the base of an ASL write_sol(...).<br><br>May be there are some "hidden" options of CBC (or OSSolverService) or "tricks" of compilation ?<br clear="all">
We'll be happy for any hints.<span class="HOEnZb"><font color="#888888"><br>-- <br>Vladimir V. Voloshinov,<br>Ph.D, head of lab.
