Overview

Currently, Waterjugs, Towers of Hanoi, Eight Puzzle, Blocks World, and Arithmetic examples from the 9.0.0 distribution all succeed in JSoar. That is to say, the full kernel of Soar 9.0.0 is implemented and functioning well. I'm working on a port of the SML layer to allow jsoar to be a drop-in replacement for csoar in any existing Java-based Soar projects.

Details

Here's the status of the porting of various source files in the kernel proper.

• Symbols - done
• Lexer - done
• Parser - done
• Reorderer - done
• Rete - functional
• No code for saving/loading binary rete
• wmem.cpp - done (org.jsoar.kernel.memory.!WorkingMemory, etc)
• tempmem.cpp - done (org.jsoar.kernel.memory.!TemporaryMemory, etc)
• prefmem.cpp - done (org.jsoar.kernel.memory.!PreferenceMemory, etc)
• osupport.cpp - done (org.jsoar.kernel.memory.OSupport)
• recmem.cpp - done (org.jsoar.kernel.memory.!RecognitionMemory)
• decide.cpp - done (org.jsoar.kernel.!Decider)
• io.cpp - done (org.jsoar.kernel.io.!InputOutput)
• decision_manipulation.cpp - done (org.jsoar.kernel.!DecisionManipulation)
• consistency.cpp - done (org.jsoar.kernel.!Consistency)
• exploration.cpp - done (org.jsoar.kernel.!Exploration, etc)
• RHS Functions
• The basic framework is in place as well as a couple of basic functions (write, etc)
• trace.cpp - done (org.jsoar.kernel.tracing.!TraceFormats)
• backtrace.cpp - done (org.jsoar.kernel.learning.!Backtracer)
• callback.cpp - done, but differently (org.jsoar.kernel.events)
• chunk.cpp - done (org.jsoar.kernel.learning.!Chunker)
• init_soar.cpp - Mostly done (decision cycle and initialization)
• print.cpp - started
• production.cpp - Mostly done (Production.java, etc). Porting additional code as needed.
• reinforcement_learning.cpp - done but untested
• explain.cpp - done

Ongoing Synchronization

Soar 9 is a moving target, this table is to help with mapping jSoar revisions to Soar 9 revisions. This information must be assumed to be incomplete. More detailed comments are provided in the commit messages.

jSoar revisions	Soar 9 revisions	Notes
302	10477	force-learn
334	10564, 10560, 10557	Bugzilla bug 1144
336	10562	state removal messages
337	10565	Bugzilla bugs 1144, 1011: marks higher-states changed when GDS removes state so impasses regenerated
338	10567, 10568	Bugzilla bug 1145 fix, but noticed rhs function actions dont-learn and force-learn unimplemented which are required before tests from csoar can be ported
352	10608	Bugzilla Bug 517 fix ported to jSoar
538	11036	Corrected select command
537	10938	Added clear of id.unknown_level on garbage collected ids.
584	10571, 10572, 10642, 10643	Bugzilla bug 234, implemented new preference semantics for better/worse filter
587	10935	Flattened out two sets of cyclical recursive functions, used in kernel garbage collection, that would cause stack overflow with long, deep working memories (such as a "linked list" of identifiers)
589	11001	Added missing clear of chunk-free problem spaces when goal is removed
