[Cbc] CBC Relative MIP gap calculation

[mg]

Hi All,
please someone can clarify how the relative MIP gap is calculated in CBC ?

I searched but I wasn't able to find the formula (I'm using 2.7.8)

For example in cplex is computed as follows:

relative_gap = | bestnode - bestinteger | / (1e-10 + | bestinteger | )

is it exactly the same ?


Thanks in advance,
Marco
