Question: what are 'self.MAXIMIZE' and 'self.MINIMIZE' used for ? #116

Closed Amgroot-w closed 2 years ago

Amgroot-w commented 2 years ago

In specific problem definitions such as 'class SubsetSum()', there is an attribute called 'self.obj_directions' in method init() which is defined by 'self.MAXIMIZE' and 'self.MINIMIZE', but there is no call in a whole algorithm run. Is this attribute just a sign? Does it have an influence on the evolution progress?

By default, jMetalPy considers that all the objective functions are to be minimized. That attribute is not taken into account in the search process.
