It's hard to understand what you are trying to do. What is a "trial solution"? Is there some randomness involved?

If you want to store multiple somethings, you best use an array: 

my @interesting_values;
for (1...1000) {
   my $r = rand;
   if ($r > 0.5) {
       push @interesting_values, $r;
   }
}

This part of your code: 

      for ($i=0; $i<$i_max; $i++) {  
 
        if ($z < $z_best) {

[download]

seems to be entirely useless, because you never set $z to anything, and there's no reason to iterate over that if-statement, since nothing in there is random or depends on $i.

Also please Use strict and warnings and declare your variables with my.
