FMultiDiscreteSpace

A struct representing a multi-discrete space (vector of integers) of possible observations or actions.

A multi-discrete space represents multiple independent discrete choices, where each dimension can have a different number of options. This is useful for representing multiple independent categorical selections, where each category may have a different number of choices.

struct FMultiDiscreteSpace : public FSpace
