a system of monomials, which has 5 equations for 5 variables , have more than one solutions,
first solution is my wanted solution,
how to eliminate other unwanted solutions?
whether
1. add more equations to eliminate unwanted solutions? how to do?
or
2. edit existing system to eliminate unwanted solutions? how to do?
a. add extra terms to some equations?
what is the cause that make it having more than one solutions?
can this reason help to edit existing system?
i succeed with adding extra equation，a1+a2+a3+a4+a5-(6+s) =0 in 3 variables case, it calculate very fast within 1 second.
but when calculating 5 variables, it evaluating a very very long time, what is the problem
without extra equation a1+a2+a3+a4+a5+a6+a7-(1+2+3+4+5+s), it get result within 1 second, but after adding this extra equation, it is like dead loop,
my surface computer run with large fans noise and very hot.
