I'm using PULP to solve an LP with CBC with a fracgap(epgap) of 0.01 (99.99%). Is there a command to return the best lower bound found after the solver finishes? So, whatever the solver is comparing the objective value to in order to know its within 0.01 and it can stop.
Objective Lower Bound command? Using PULP with COIN_CMD/CBC/CLP

Sorry but Pulp does not return the best bound of the solution, with COIN_CMD(). I think it is printed to stdout if msg=1 is used if you just what to see what it is.
