Hi,

when I specify an instance without variables, then a call to osinstance->getNumberOfBinaryVariables() fails.

I called osinstance->setVariableNumber(0), but when I request something like the number of binary variables, then it throws an error "no variables defined". Shouldn't it just return 0?

When I skip this and try to solve my instance with Clp, then I get the same error thrown from the call to solve().

I had expected that such an instance is easy to solve, since it just consists of evaluating objective and constraints and deciding for feasibility.

Stefan
