The construction algorithm of the schreyer frame in resol.c
has contained a bug. It has not constructed the minimal schreyer frame.
The bug is now fixed. See minimal-note-ja.txt for details and test data.

ScheckIfSchreyer(): it checks if grade (grading function)
is module1v (grading without vector component).
Note that ring_of_differential_operators switches grade to
module1.

Found a reason why the strategy fails.
It is because the schreyer skelton contains an element
of the form [1,f].  This bug will be fixed soon.

A list of todo (e.g., init<m> )

Succeeded to construct the V-minimal resolution for 1/(x^3+y^3+z^3).
The betti numbers are 4,5,2.

Sminimal(V, opt) : opt can be "homogenized"
Several test codes are added.
test14, test15, test16 : minimal resolution of GKZ systems.
We still have a trouble in the strategy for non-term orders.

Revision 1.4 / (download) - annotate - [select for diffs], Fri Jun 9 08:04:54 2000 UTC (24 years, 5 months ago) by takayama

Changes since 1.3: +449 -2 lines
Diff to previous 1.3 (colored) to selected 1.1 (colored)

Bug fix of Sminimal().
test_ann3(f) computes the V-minimal free resolution for
the laplace transform of the annihilating ideal 1/f.
It also checks if the obtained one is exact or not by using
IsExact_h().
Sminimal() still contains troubles.
For example, it does not work for [x^2+y^2, x*y] with
(-1,-1,1,1) weight vector.

Revision 1.3 / (download) - annotate - [select for diffs], Thu Jun 8 08:37:53 2000 UTC (24 years, 5 months ago) by takayama

Changes since 1.2: +26 -1 lines
Diff to previous 1.2 (colored) to selected 1.1 (colored)

New command:
    SisExact_h :  it calls sm1 macro isExact_h
Function for debugging:
   test10() in minimal-test.k, which is used to check if the Schreyer
   resolution constructed Sschreyer (LaScala-Stillman's algorithm) is
   exact or not (bug).

Branch: MAIN

I added some codes to check if the output is minimal or not.
