Hello,
For my work i must solve a system of 9 equation with 5 unknown (I paste the
system at the end of my mail).
This system is very nonlinear and I have tested Newtons method to solve it but
I converge not necessarily on the true solution because it seems truly to
depend of the initialization of my unknown.
So, I have find the Simulated annealing to find the global minimum and the true
solution but in the test.c of siman program I have just view an example of one
equation with many unknown and not an example of a system of equation with many
unknown.
My question is how can I use this program with my system of equation?
Thank you by advance.
