Worked Examples

What actually happens in order to execute a thought process from start to finish? This page answers that through some detailed examples.

Solve “3 + 8”

The processing of user command “3 + 8” occurs as follows:

Step	Processor	Description
1	User request	“3 + 8” enters input sense
2	RequestCommandInterceptor	Emits TextRequestEvent to WM, holding text “3 + 8”
3	ExpressionAndEquationParseProcessor	Detects TextRequestEvent. Pre-programmed to “just know” how to parse expressions. Emits PerceptEvent containing parsed expression as a syntax tree
4	ExpressionEvaluationProcessor	Detects PerceptEvent flagged with pre-programmed Expression concept. Pre-programmed to “just know” how to evaluate expressions. Emits PerceptEvent containing resultant number, flagged as a result
5	ExpressionResponseProcessor	Detects result PerceptEvent and presence of a user request. Emits ActionEvent with text of response “11”
6	SpeakActionProcessor	Detects ActionEvent. “Speaks” response text

Solve “3 + ? = 8”

Note: this is a work-in-progress.

The processing of user command “3 + ? = 8”, without user interaction to help the process, occurs over about 3 stages, as follows:

Step	Processor	Description
1.0	User request	“3 + ? = 8”
1.0	RequestCommandInterceptor	Emits TextRequestEvent to WM
1.1	ExpressionAndEquationParseProcessor	Emits PerceptEvent with partially parsed expression
1.2	EquationEvaluationProcessor	Does nothing. Unable to process
2.0	StuckThoughtInterceptor	Emits StuckThoughtEvent
2.1	FindMatchingConceptProcessor	Assumes need to find concepts due to StuckThought, emits MemorySearchRequest
2.2	LongTermMemorySearchProcessor	Searches LTM, emits MemoryEvent
2.3	FindMatchingConceptProcessor	Assumes need to find concepts due to StuckThought, finds one or more in WM, so stops
2.4	(…)	What selects one of the concepts to try against? First cut: for now just pick single greedy option, in both ConceptInferenceProcessor and GapFillingProcessor.
2.5	ConceptInferenceProcessor	Attempts to infer an identification of concept for ‘?’ based on matching against concepts in WM. Emits a Percept if it discovers something better than what’s already present. Emit new Percept theorising that ‘?’ is a number.
2.6	GapFillingProcessor	Attempts to fill gap in partially parsed expression using concept/concepts available in WM, including any inferred concepts if present. Emit new Equation Percept, with ‘?’ tagged as a number.
2.7	EquationEvaluationProcessor	Needs to kick in a try again against new equation percept. Will fail once again.
3.0	StuckThoughtInterceptor	Emits StuckThoughtEvent
3…	(…)	[WIP] Now start employing strategies to guess at number value of ‘?’
x.x	FindMatchingConceptProcessor	[WIP] Last found concept(s) not good enough, tries again
