Member Function Documentation

virtual HandleSeq opencog::ForwardChainerCallBack::apply_rule ( FCMemory &  fcmem )

pure virtual

apply chosen rule. the default will wrap a custom PM callback class. i.e invokes _pattern_matcher.

Returns

a set of handles created as a result of applying current choosen rule

Implemented in opencog::DefaultForwardChainerCB.

Here is the caller graph for this function:

virtual Handle opencog::ForwardChainerCallBack::choose_next_source ( FCMemory &  fcmem )

pure virtual

choose next source from the source list

Returns

a handle to the chosen source from source list

Implemented in opencog::DefaultForwardChainerCB.

Here is the caller graph for this function:

virtual HandleSeq opencog::ForwardChainerCallBack::choose_premises ( FCMemory &  fcmem )

pure virtual

Choose additional premises for the rule. an object holding the current source/target and other inform ation of the forward chaining instance.

Returns

a set of Handles chosen as a result of applying fitness criteria with respect to the current source.

Implemented in opencog::DefaultForwardChainerCB.

virtual std::vector<Rule*> opencog::ForwardChainerCallBack::choose_rules ( FCMemory &  fcmem )

pure virtual

Choose a set of applicable rules from the rule base by selecting rules whose premise structurally matches with the source. an object holding the current source/target and other inform ation of the forward chaining instance.

Returns

a set of applicable rules

Implemented in opencog::DefaultForwardChainerCB.
