This suite of incremental STRIPS planning encodings implements diverse methods.
|
||
|
|
The included encoding files provide the following functionalities:
|
||
|
|
|
||
|
|
- preprocess.lp: static analysis of potentially relevant actions
|
||
|
|
+ Parameters: _closure (default value: '3')
|
||
|
|
* Value '1': forward chaining of effects w.r.t. initial variable values
|
||
|
|
* Value '2': backward regression of effects w.r.t. goal variable values
|
||
|
|
* Value '3': both forward chaining and backward regression of effects
|
||
|
|
* Otherwise: off (simply take all actions as given)
|
||
|
|
|
||
|
|
- strips-incremental.lp: sequential and parallel planning encoding variants
|
||
|
|
+ Parameters: _parallel (default value: '0')
|
||
|
|
* Value '1': "forall" parallel actions that can be arranged in any sequence
|
||
|
|
* Value '2': "exists" parallel actions that can be arranged in some sequence
|
||
|
|
* Otherwise: sequential actions
|
||
|
|
|
||
|
|
- redundancy.lp: enforcement of 'redundant' actions to constrain parallel plans
|
||
|
|
+ Remarks:
|
||
|
|
* Only relevant together with parallel actions
|
||
|
|
* Encoded constraints seem rather ineffective though
|
||
|
|
* Heavy space overhead in combination with "exists" parallel actions
|
||
|
|
|
||
|
|
- postprocess.lp: plan feasibility checking and conversion to sequential plan
|
||
|
