I have tested Etienne Grossmann's 'downsimplex' routine and it was
successful in computing the example functions from the code
documentation, however, the documentation is not clear enough and I am
inexperienced enough in linear programming to understand how I could use
this routine to solve the following problem:
maximize(or minimize) z = 3x(1) + 2x(2) +x(3)
subject to 2x(1) + x(2) + x(3) <= 150
with x(1)>=0,x(2)>=0,x(3)>=0
I understand that Octave has been integrating more optimisation tools so
I never expected the optimisation process to be a simple one, however I
do need to know if this routine has the ability to adress this type of
linear programming problem and what steps I might take to find further
documentation on its use.
Thanks for taking the time to read,
michael
