Solving two nonlinear equations with two knowns
Dear R users,
I have two nonlinear equations, f1(x1,x2)=0 and f2(x1,x2)=0. I try to use optim command by minimize f1^2+f2^2 to find x1 and x2. I found the optimal solution changes when I change initial values. How to solve this?
BTW, I also try to use grid searching. But I have no information on ranges of x1 and x2, respectively.
Any suggestion to solve this question?
Thanks,
Kate

NOTE1: Code size increase in SPEC2006 was mainly attributed to benchmark
"astar", which increased by 86%. Removing this outlier, we get a more
reasonable increase of 0.58%.
NOTE2: There is a patch up for review on Phabricator to enhance the partial
inliner with the presence of profiling information (

The register-starved i386 target benefits the most. This is the change in execution time for the SPEC benchmarks that change by more than 3% (minus means faster, plus slower):
Targeting i386:

-8.8% 473.astar
-7.4% 401.bzip2
