Multiples syntaxtically different patches for SQRT

[martinezmatias]

Hi @SophieHYe
One point to discuss about the patches for SQRT generated by jGP.
One of the patches is:

-        while (Math.abs(x-approx) > epsilon) {
-            approx = 0.5f * (approx + x / approx);
-        }
+        approx = 0.5f * (approx + x / approx);
+		approx = 0.5f * (approx + x / approx);
+		approx = 0.5f * (approx + x / approx);
+		approx = 0.5f * (approx + x / approx);
+		approx = 0.5f * (approx + x / approx);
+		approx = 0.5f * (approx + x / approx);
+		approx = 0.5f * (approx + x / approx);
         return approx;
     }

The way to produce the failing tests to pass is to unwrap the while, at least, 6 times.
This mean that other plausible patches adds more + approx = 0.5f * (approx + x / approx); and the test continue passing. So, we can add 100 assignments and the test will always pass.

Do you think we should consider one patch or multiple (even syntactically different) patches?
WDYT?
