Detailed Description

Policy is a class that represents a policy for a single agent.

It contains the notion of the depth of a policy: a positive number that specifies for how many time steps this policy is specified. I.e., if depth < horizon, the object represents a partially specified policy (specified for time steps 0,...,depth-1)

size_t Policy::_m_depth

private

The depth of this joint policy.

The depth of the policy is the number of stages for which it specifies actions. It ranges from:
0 (the empty policy),
1 (a policy specified only for ts=0),
: MAXHORIZON (a policy specified for all stages, the default value).
