Hi, I was optimizing my code and noticed that I got a bunch of brute force searches for an extremum of a function of more then one value like so:
(bind (((best-x best-y best-z)
(iter outer
(for x ...)
(iter (for y ...)
(iter (for z ...)
(in outer
(finding (list x y z) maximizing (objective x y z))))))))
...)
The above code is causing excessive consing in the (list x y z) part
and one can't specify (values) instead.
With the attached patch I can write:
(bind (((values best-x best-y best-z)
(iter outer
(for x ...)
(iter (for y ...)
(iter (for z ...)
(in outer
(finding (values x y z) maximizing (objective x y z))))))
...)
which does not cons and results in faster code.
finding-values.patch
