|
||
<dd><p>Base class (template) for functional envs.</p>
|
||
<p>This API is meant to be used in a stateless manner, with the environment state being passed around explicitly.
|
||
That being said, nothing here prevents users from using the environment statefully, it’s just not recommended.
|
||
A functional env consists of the following functions (in this case, instance methods):</p>
|
||
<blockquote>
|
||
<div><ul class="simple">
|
||
<li><p>initial: returns the initial state of the POMDP</p></li>
|
||
<li><p>observation: returns the observation in a given state</p></li>
|
||
<li><p>transition: returns the next state after taking an action in a given state</p></li>
|
||
<li><p>reward: returns the reward for a given (state, action, next_state) tuple</p></li>
|
||
<li><p>terminal: returns whether a given state is terminal</p></li>
|
||
<li><p>state_info: optional, returns a dict of info about a given state</p></li>
|
||
<li><p>step_info: optional, returns a dict of info about a given (state, action, next_state) tuple</p></li>
|
||
</ul>
|
||
</div></blockquote>
|
||
<p>The class-based structure serves the purpose of allowing environment constants to be defined in the class,
|
||
and then using them by name in the code itself.</p>
|
||
<p>For the moment, this is predominantly for internal use. This API is likely to change, but in the future
|
||
we intend to flesh it out and officially expose it to end users.</p>
|
||
<p>Initialize the environment constants.</p>
