                              MaceCommand

A MaceCommand specific to the Mace model builder. It contains the a print_assumptions() method that is used to print the list of assumptions in multiple formats.

Method Details [hide private]

__init__(self, goal=None, assumptions=[], timeout=60)
(Constructor)

source code 
Parameters:
  • goal (logic.Expression) - Input expression to prove
  • assumptions (list of logic.Expression) - Input expressions to use as assumptions in the proof.
  • timeout (int) - number of seconds before timeout; set to 0 for no timeout.
Overrides: api.ModelBuilderCommand.__init__

convert2val(self)

source code 

Transform the output file into an NLTK-style Valuation.

Returns: nltk.sem.Valuation
A model if one is generated; None otherwise.

_make_model_dict(num_entities, values)
Static Method

source code 

Convert a Mace4-style relation table into a dictionary.

Parameters:
  • num_entities (int) - the number of entities in the model; determines the row length in the table.
  • values (list of int) - integers that represent semantic values in a Mace4 model.

_make_model_var(value)
Static Method

source code 

Pick an alphabetic character as identifier for an entity in the model.

Parameters:
  • value (int) - where to index into the list of characters

show_model(self, format=None)

source code 

Print out a Mace4 model using any Mace4 interpformat format. See http://www.cs.unm.edu/~mccune/mace4/manual/ for details.

Parameters:
  • format (str) - Output format for displaying models. Defaults to 'standard' format.

_transform_output(self, format)

source code 

Transform the output file into any Mace4 interpformat format.

Parameters:
  • format (str) - Output format for displaying models.
