Once you have gotten the values (in the node LP solution) for all variables, you can loop through the integer variables, computing the absolute difference between the value and the nearest integer. If any absolute difference exceeds the integrality tolerance (IloCplex::Param::MIP::Tolerances::Integrality), break out of the loop and treat the solution as not ...

The type of a variable cannot be changed. However, it can be overwritten for a particular model by adding an IloConversion object, which allows you to specify new types for variables within that model. When ILOG CPLEX finds a conversion object in the active model, it uses the variable types specified in the conversion object instead of the original type ...

A solution can be found here c-using-clock-to-measure-time-in-multi-threaded-programs. Since you do not limit the threads, Cplex will span as many as there are cores. You are counting the cpu time (and since each core contributes all of its running time) you see a much larger value. I think you are interested in the wall-time of the process. $892/120 \...
