129.11.02
2        ref for ncstruct introduced,
3        used in extra.cc ("PLURAL"), rCopy0, rKill
4        new routine ncKill
5
629.11.02
7        qring q=system("twostd",i); is introduced and tested
8        file: exterior1.tst
9        todo: forbid the use of non-twosided ideals
10
116.12.02
12        DONE: option(redTail) is implemented and tested
13        file: exterior2.tst
14        DONE(11.12.02) todo: in twostd, running from qring should be
15        done another std() in order to get reduced result
16       
17        DONE: buckets in multiplication (p_Mult_mm, mm_Mult_p)
18        version 1.17 - add cvs -m "buckets added", not
19        just nCopy
20        todo: syz(i) with the canonical method, think about
21        Schreyer and LaScala (double homogenization)
22        Print(p) at gr_kstd2.cc:877 is commented out
23       
2423.01.03-
2531.01.03
26        Updated multiplication:
27        now we search for the shortest path with nc_uu_Mult_ww_horvert
28        An old code is called nc_uu_Mult_ww_vert, is used by default.
29       
30        Further on, we should compute metrics.
31
32        A function added:
33        matrix ncMatPrint(int a, int b, ring r, int metric)
34        /* returns matrix with the info on noncomm multiplication */
35Before these changes, we copied the exec to Singular.Jan.
36
3731.01.03
38        DONE syz, nres, mres;
39        small problems with minres.
40
41until
4217.03.03
43        fixed: minres, ideal multiplication, maps, syz
44        balanced the use of buckets in mult and bracket
45        added quasicommutative stuff in multiplication
46        gained about 30% speedup
47
4818.03.03
49        fixed: extra "type print" in ring.cc
50        new strategy of bucket used in bracket
