# Which Simulator Should I Use?

The simulators in this package provide interaction with simulations of MDP and POMDP environments from a variety of perspectives. Use this page to choose the best simulator to suit your needs.

## I want to run fast rollout simulations and get the discounted reward.

Use the Rollout Simulator.

## I want to evaluate performance with many parallel Monte Carlo simulations.

Use the Parallel Simulator.

## I want to closely examine the histories of states, actions, etc. produced by simulations.

Use the History Recorder.

## I want to step through each individual step of a simulation.

Use the stepthrough function.

## I want to visualize a simulation.

Use the DisplaySimulator.

Also see the POMDPGifs package for creating gif animations.

## I want to interact with a MDP or POMDP environment from the policy's perspective

Use the sim function.
