struct FDiscreteSpace : public FSpace

Source: Source/Schola/Public/Common/Spaces/DiscreteSpace.h

Dependencies: ConstSpaceVisitor, FPoint, SpaceVisitor

A struct representing a discrete space of possible observations or actions.

A discrete space represents a single choice from a finite set of options, numbered from 0 to High-1. This is commonly used for discrete action spaces where an agent selects from a fixed set of actions (e.g., move left, move right, jump).

High

int High = 0

The exclusive upper bound (maximum value + 1) for this discrete space.

The lower bound is always 0. For example, High=2 gives valid values {0,1}.
