[Cbc] branchAndBound with a hot-start solution

[Kibaek Kim]

Dear John,

Thanks very much for your prompt response. But, now I am getting linking errors. I am compiling the codes on Mac OS X 10.9.5 (2.8 GHz Intel Core i7) using gcc4.8. I have attached config.log and make.log.

Best,
Kibaek

I have attached a simple code, mps file and hot-start solution file to reproduce results. The code will read mps file and hot-start solution file and try solving the problem. However, the following three settings result in different behaviors:
>> 1. CbcStrategyDefault strategy(0); // assertion fail
>> 2. CbcStrategyDefault strategy(0, 5, 5); // infinite loop
>> 3. CbcStrategyDefault strategy(1); // success
