check_pomdp: Check POMDP

In conservation-decisions/smsPOMDP: POMDP problem solver: When to stop managing or surveying cryptic threatened species ?

Description

Checks if input matrices are compatible to form a POMDP

Usage

check_pomdp(transition, observation, reward)

Arguments

transition	Transition matrix between states, can be computed using tr. Array, dimensions = SxSxA with S number of states and A number of actions (positive)
observation	observation matrix for each action, can be computed using obs. Array, dimensions = SxOxA with S number of states, O the number of observations and A number of actions (positive)
reward	reward matrix, can be computed using rew. Matrix of A rows and S columns, with S number of states and A number of actions (positive)

Details

Checks the compatibility of dimensions of the input matrices (same number of states, actions), are the transition matrices stochastic and square,

Value

Bool, TRUE if the inputs are compatible to form a POMDP, FALSE otherwise
