• File src/solver.rs — part of check-in [cd30b6f272] at 2018-06-26 21:17:34 on branch error-handling — master: Subgradient extension callback may return an error. This callback eventually calls a method of the oracle and may fail with some user error. This error is now returned to the master problem and finally back to the solver. (user: fifr size: 36955)
