NLPUC: Hooke-Jeeves-Vala: Almost all good in this impl.: #52

Closed rgolubtsov closed 7 years ago

Except one thing, there're all the reasons to claim that Vala implementation of the Hooke and Jeeves alg. is almost finished and is quite smart. But that thing is zeroed funevals value:

`... After 0 funevals, f(x) = 1.0007e+00 at x[ 0] = 3.2121e-01 x[ 1] = 7.9306e-02 x[ 2] = 1.3822e+00 x[ 3] = 1.9121e+00

After 0 funevals, f(x) = 9.6673e-01 at x[ 0] = 3.0206e-01 x[ 1] = 8.5687e-02 x[ 2] = 1.3799e+00 x[ 3] = 1.9057e+00

HOOKE USED 27 ITERATIONS, AND RETURNED x[ 0] = 3.5318901e-01 x[ 1] = 1.0273157e-01 x[ 2] = 1.3737259e+00 x[ 3] = 1.8886365e+00 ...`

:+1: Let it be until funevals will be fixed.
