This is important when a variable can only range between +(-1 .. 1) and you have declared that it can range from (-100 .. 100). +Because of the much wider search space \, there is less likelyhood +of finding anything useful \, or at least make the search times longer +due to higher failure rates.; +#X text 35 147 If you are unsure of what the ranges are \, you can +either figure them out mathematically \, or use the "brute-force" method +and iterate over ranges of the defined parameters. The points that +return a fractal (even ones that converge) will give an indication +as to the acceptable ranges for each param. Once you have determined +those ranges \, adjust them in your '*.frac' file and re-make the external +for your fractal. (Or you can just edit the Macros in the C code \, +if you are comfortable with that.); -- cgit v1.2.1
