## Complexity of some algorithm in computat...

Hi Dears,

I studied the concept of Grobner bases and some algorithm for computing them. I understood that the computation of grobner bases is related to the term ordering. Also, I knew that LEX ordering is very expensive. So, it is good idea to use the Grobner basis conversion algorithms such as FGLM and Grobner walk algorithm. Now, I want to know concerning the complexity of these algorithm (Buchbergers algorithm, F4 and F5 algorithm, FGLM algorithm and Grobner walk). I hope my question be appropriate in this site,

I am looking forward to hearing from you.

## How can I draw the solution of a 3d line...

Maple 18

Hi dears,

How can I draw the solution of the following 3d linear inequalities in Maple?

A:={-x-y+3*z >= 0, -x+2*y >= 0, 3*x-2*y-z >= 0, x > 0, y > 0, z > 0}

I am looking forward to hearing from you

Sincerely yours.

## How can I detect two equivalent matrices...

Maple

Hi dears,

How can I detect two equivalent matrices? Is there any Maple command for this?

Also, Is there any command to verify that two matrices have the same Smith normalform?

Sincerely yours

## Could you please introduce me some examp...

Maple

I need  some examples s.t. the computation of their lexicographic Groebner basis is heavy?

Thank you so much.

## Maximal independent set of ideal...

Maple

What is the maximal independent set of monomial ideal\$<c^4a^3b>\$ in \$K[a,b,c]\$?
