I have several simultaneous equations to be solved. There are some
parameters in these equations that have not been decided yet. I try to
find out with which values of the parameters these equations could be
solved. That is, sometimes they can not be solved to get explicit

1. Is it a good idea to randomly choose a set of values for the
parameters (5 of them) and try to solve the equations, and if fail to
get explicit answer, iterate this process?

2. How could I control the iterating progress, i.e., let the program
to stop and print out the results once any explicit solution is

3. How could I suppress any output (error or warning messages) if the
equations are not solvable and just let the iteration to go on?
