This is a record of the regression analyses obtained by running the logs through
the help system.
The actual log files themselves are not stored in CVS since they are very long.
Fall2006-anon.dat: original log file
Fall2006-anon.dat.can: canonicalized version
Fall2006-anon.June-7-2007.can.diff: This has not been analyzed.

Diff against Fall2006-anon.dat.can has 769736 lines and has not been analyzed.
Winter2007-USNA-treacywintersgill.dat: original log file
Winter2007-USNA-treacywintersgill.June-8-2007
Winter2007-USNA-treacywintersgill.June-27-2007
Diff between June 8 & June 27:
Bug #1297
Bug #1299
Winter2007-USNA-treacywintersgill.July-9-2007
Diff between June 27 & July 9:
fix to code-char
typos in write-loop-rule2 WRITE-CHARGE-FORCE-BFIELD-MAG define-line-integral
LENS-EQN-IMAGE-AT-INFINITY
add z-component given to problems where vectors specified component-wise
control plus-minus printed out differently
Winter2007-USNA-treacywintersgill.July-14-2007
Diff between July 9 and 14:
didn't do complete check, but differences appear to be due only
to changes to problem definitions (POT4* etc.)
Winter2007-USNA-treacywintersgill.July-16-2007
Diff was too messy
temporarily undo changes to reweighting in (contextualize ...).
Winter2007-USNA-treacywintersgill.July-18-2007
Diff between July 14 and July 18:
change in Help/Entry-API by Anders (NIL -> NIL;VALUE)
lots of other stuff ..
fix bug in testing for done-already:
Winter2007-USNA-treacywintersgill.July-20-2007
Diff between July 14 and July 20:
none, after canonicalization
Use EntryTests to determine matches to student entries:
Winter2007-USNA-treacywintersgill.July-23-2007
Fix bug: use unify for equivalence of SystemEntry-prop
Winter2007-USNA-treacywintersgill.July-24-2007
Diff between July 24 and July 14:
after canonicalization, all diffences due to
fix of the SytemEntry equivalence.
Winter2007-USNA-treacywintersgill.August-13-2007
Winter2007-USNA-treacywintersgill.August-13-2007.can
Diff between July 24 and August 13:
differences from additional use of random in determining slot,
fix error with remove-nil-keywords, changing blank space around "=",
remove superfluous time slots in various hints (in KB/vectors.cl)
change to hash function used in defining derivatives.
fix bug in SWITCHED-X-AND-Y-SUBSCRIPT (so it now applies)
Student equations setting unused zero components of vector equation to zero no longer flagged as error.
Other changes that are not necessarily good:
WRONG-TRIG-FUNCTION instead of USED-MAGNITUDE-INSTEAD-OF-COMPONENT
Suggestion to enter B field magnitude instead of z-component of velocity
UNDIAGNOSED-EQN-ERROR instead of MISSING-NEGATION-ON-VECTOR-MAGNITUDE
DEFAULT-SHOULD-BE-NON-ZERO instead of DEFAULT-SHOULD-BE-UNKNOWN
Also, there seems to be a number of error interpretations that have been
changed due to the changes in the use of the random number generator for tie-breaking.
Diff between September 15 and August 13 2007:
Anders changes to scoring rules (I assume these are OK).
Remove unused :error in slit problem givens.
Change number on problem pot1b pot2c.
Remove zero term in projection equations.
Change hint for drawing displacement vector.
New operator draw-accel-given-zero-net-force replacing some accel-at-rest.
Change to cross product dropping known zero terms changes:
Associated equations now have an explicit zero.
Unneeded components are no longer prompted by the help.
Unwanted side effect: if the general form is used, the help
system can complain the student is using unneeded variables.
Diff between October 5 and Sept. 15, 2007.
now have time slot in relative-position def-qexp
lots of changes to scoring, including capitalization of subscores
change naming for B-field variable
fix wording on projection equation hint.
remove keyword pairs not done by subst-bindings
operators for defining angle-between changed around.
There are still 112,000 lines of diff that are not fully analyzed.
Some are:
There are some zero projections which are no longer recognized.
The previous fix, using an implicit-eqn, would also remove
zero projections which are needed for the solution.
Internal form of cross and dot now contain all terms.
Hints for needed zero projection equations where it used to say "done."
Some change from DRAW-COMPO-FORM-AXES to DRAW-PROJECTION-AXES due to
removal of implicit-eqn from compo-parallel-axis.
Wording of draw line hint.
New angle-direction for lines does not allow substitution
into snells law formula when angles are known.
Need write-angle-direction-known to also work for lines. Bug #1407
