	* ASMModelSwarm.m ([AsmModelSwarm -getModelTime): get
	method to allow other classes to find out what Swarm "time step"
	the model is on.

2001-02-07  Paul E Johnson  <[e-mail]>

	* Output.m ([Output -dumpParametersModel:BFAgent:]): New method,
	Model can tell it to do this and it will decide whether to use
	Lisp or HDF5 and create a time-stamped parameter output file.

	* Output.m([Output -createEnd]): runTime is now calculated at
	create time, so that any output files can be time stamped.

	* main.m (main): Now it will dump parameter values at the end of
	the run, whatever Output is supposed to dump, will get dumped,
	with a time-stamp.
	
	* ASMModelSwarm.m (buildObjects): get rid of conditional round
	output object creation/setting. We are always setting up an output
	object, whether or not the user wants to actually output
	data. This gets rid of one layer of stupidity.

	* ASMModelSwarm.m (initOutputForDataWrite): delete this method and
	associated IVAR

	* ASMModelParams.m ([ASMModelParams +createBegin:aZone]): added
	probe for setOutputData

	* asm.scm (cons): added setOutputForData 1 to initialize it.

2001-02-06  Paul E Johnson  <[e-mail]>

	* BFCast.m: added import of <misc.h> 

2000-06-16  Paul Johnson  <[e-mail]>

	* main.m (main): lispAppArchiver loading for ASMBatchSwarm

	* ASMBatchSwarm.m ([ASMBatchSwarm -buildObjects]): batch model
	load parameters from asm.scm.  Adjust asm.scm accordingly.

2000-06-08  Paul Johnson  <[e-mail]>

	* Output.h:Removed the following methods:
		-setNumBFagents: (int)BFagents;
		-setInitHolding: (float)Holding;
		-setInitialCash: (double)initcash;
		-setminHolding: (double)holding   minCash: (double)minimumcash;
		-setIntRate: (double)Rate;
			      
	         -setBaseline: (double)theBaseline;
		 -setmindividend: (double)minimumDividend;
	      -setmaxdividend: (double)maximumDividend;
	      -setTheAmplitude: (double)theAmplitude;	
		-setThePeriod: (int)thePeriod;
	       -setExponentialMAs: (BOOL)aBool;
			        
		-setMaxPrice: (double)maximumPrice;
		-setMinPrice: (double)minimumPrice;
		-setTaup: (double)aTaup;
		-setSPtype: (int)i;	
		-setMaxIterations: (int)someIterations;
		-setMinExcess: (double)minimumExcess;
		-setETA: (double)ETA;
		-setETAmin: (double)ETAmin;
		-setETAmax: (double) ETAmax;
		-setREA: (double)REA;
		-setREB: (double)REB;

		-setSeed: (int)aSeed;

		-setTauv: (double)aTauv;
		-setLambda: (double)aLambda;
		-setMaxBid: (double)maximumBid;
		-setInitVar: (double)initialVar;
		-setMaxDev: (double)maximumDev;
 

	* ASMModelSwarm.m ([ASMModelSwarm): removed parameter setting
	activity to separate class called ASMModelParams.  That class also
	has probes now. So no more need for createBegin.  Deleted all
	IVARS from ASMModelSwarm.h that are in the param object, use -> to
	get params back from parameter object.

	* ASMModelSwarm: Removed initParamForWrite. Now archiver can put
	shallow and it works fine.

2000-06-02  Paul Johnson  <[e-mail]>

	* BFagent.h (Agent): Closed memory leaks by [index drop]. Still
	some small leak in the GA code.

2000-06-01  Paul Johnson  <[e-mail]>

	* BFagent.m : Added BitVector usage, added methods -updateActiveList and
	-collectWorldData.

	* BitVector.h,m: Created this class, used in both BFagent.m and BFCast.m.

2000-05-31  Paul E. Johnson  <[e-mail]>

	* BFagent.m:  Crossover:  added  calculation  of  new  forecast's
	Strength,   based   on   bfagent   code.   Tried   to   sort   out
	mistake/differences between bfagent and BFagent.

	*BFagent.m: moved the "world getting" capability from
	+prepareForTrading to -prepareForTrading. Each agent gets its own
	copy of the world now. No more need to execute +prepareForTrading
	anymore.


	* BFagent.m: Use "updateSpecfactor" whenever conditions are changed in a
	BFCast.

	* BFagent.m: prepareForTrading: commented out previous code to select
	activeList on grounds it was false. Instead, created routine to
	check forcast's bits, and for each non 00 bit, check if it matches
	the world.  There's some fat to be removed here, but at least it
	is not logically wrong.

	* BFCast.m: added "updateSpecfactor" method.


2000-05-30  Paul Johnson  <[e-mail]>

	* BFagent.m: Found vital flaw in original ASM model--forecasts
	were not updated. Dynamics look more persuasive after
	fixing. Created "updateForecast" method in BFCast class to do this.

	* BFagent.m (prepareForTrading): lActiveList commented out. It is never used!

	* ASMModelSwarm.m: [BFagent init] no longer needed.
	[BFagent didInitialize] no longer needed.

	
	* BFagent.m: Note makebittables is now moved to BFCast.m.
	"free" method removed, now handled by drop method in BFCast.m
	Commented out usage of lActiveList, since it is a memory leak and seems to serve no purpose

2000-05-28  Paul E. Johnson  <[e-mail]>

	* BFCast.m: This is a new class that has the same basic structure
	as the BF_Cast struct that used to be in BFagent.h.  It has
	get/set methods for all the variables. Most importantly, is has
	the makebittables() function and the bit management
	interface/functions.  All bit management is handled by methods
	like getConditions, getConditionsBit: , setConditions:
	setConditionsBit: To:, and so forth.

	*  BFagent.m:  A complete  clarification/reconstruction  of  the
	BFagent  code, that  eliminates as  much  as possible  any of  the
	"spaghetti" flavor of the previous BFagent code.

	1. Separates into 2 new classes the 2 big structs in BFagent.h,
	and creates an interface for putting information into BFCasts (the
	bit string forecast class) and BFParams ( the parameter keeping
	object).  The beauty of this is that almost all (99.5%) of the bit
	math is moved into that separate class, and the BFagent can change
	the values of bits by just telling a forecast object to do it, as
	in
	
       [heyYouForecast setConditionsbit: 22 To: 1];

	2. Complete and total elimination of all global variables.

	3. Replacement of pointer-based "homemade" linked lists with Swarm
	Arrays and Lists.  This eliminates the need for "hands on" processing
	of dynamic memory.

	4. Conversion of the GA functions into Obj-c methods. They do the
	same thing, but don't require all those global declarations.  Now
	more arguments are passed into these methods so they know which
	lists to manipulate without having all those global variables
	sitting around.

2000-05-25  Paul Johnson  <[e-mail]>

	* BFagent.m: changed IVAR "p" to "privateParams" to ease editing
	and clarify things.  There is no current purpose in keeping a
	private param object, but at some future time it may be useful,
	especially if there are subclasses from BFagent.
	([BFagent -performGA]): Everything is as local as possible.
	Eliminated all possible global vars.

2000-05-25  Paul E. Johnson  <[e-mail]>

	* BFagent.m ([BFagent -performGA]): moved GA functions inside
	performGA method, so they have automatic access to Ivars and we no
	longer need to declare all those global variables or functions.  *

	* BFParams.m: new object to hold parameters, which were previously
	kept in a struct.

2000-05-24  Paul Johnson  <[e-mail]>

	* BFagent.m: cleared out ^M from Windows
	([BFagent +init]): changed probs and bits from class variables to
	local arrays in this method.  They are only used in this
	method. MAXCONDBITS is a compile-time variable, no need for
	dynamic memory.
	

2000-05-07  Paul E. Johnson  <[e-mail]>

	* ASMModelSwarm.m ([ASMModelSwarm +createBegin:]): This is the
	first official entry of the Changelog.  Before Brandon Weber
	released the ASM code, I was working against a copy of the code
	from the SFI's cvs.  There are some slight differences, and
	figuring them out was not too tough.  Anyway, the major idea is to
	get rid of as many "ad hoc" do-it-yourself components, replacing
	them with off-the-shelf Swarm things.  The patch file
	"ASMpatch1-pj.txt" implements the changes that bring the random
	number usage "up to date" with Swarm.
