 Post subject: how to compute all combination of system of polynomials
PostPosted: Fri Sep 12, 2014 11:41 am 
want to classify all combination of system of polynomials with hilbert series

maple code got out of memory

AllMatrices := proc (A::set, k::posint, n::posint)
local B, C, E:
B := [[]]:
C := proc ()
B := [seq(seq([A[i], op(B[j])], i = 1 .. nops(A)), j = 1 .. nops(B))]:
end proc:
E := (C@@(k*n))(B):
seq(Matrix(k, n, E[m]), m = 1 .. nops(A)^(k*n));
end proc:
mm := AllMatrices({0, 1}, 3, 3);

GetRing := proc(sol)
ringequation := 0;
mono1 := 0;
for j from 1 to 3 do
mono1 := 1;
for i from 1 to nops(sol[1][j]) do
mono1 := mono1*op(i, sol[1][j]);
od:
ringequation := ringequation + mono1;
od:
return ringequation;
end proc;

with(LinearAlgebra):
polylistresult := [];
for i from 1 to nops([mm]) do
sol := MatrixMatrixMultiply(Matrix([[a,b,c]]), op(i,[mm]));
sol := GetRing(sol);
polylistresult := [op(polylistresult), sol];
od:
gaga := polylistresult;
nops(polylistresult);
polylistresult := [op(polylistresult), op(gaga)];
nops(polylistresult);
polylistresult := [op(polylistresult), op(gaga)];
nops(polylistresult);
with(combinat):
gg := permute(polylistresult, 3);
Error, (in combinat:-permute) Maple was unable to allocate enough memory to complete this computation. Please see ?alloc
