SD graph turns to a line

[mervkafa (merve deniz tak)]

Hi,
When I start my optimization, the SD graphs looks they work fine but later, some fitness objective SD graphs turn to a line. What does that mean? Is it a error or what should I understand from this?
Any help would be nice.

Best Method for Maximizing Objectives?

Hey all, Is 1/x the best method to maximize values? When I have a 0 value, it becomes infinite. To compensate, I am adding 0.01 to the values before 1/x, however, I know this is not ideal in every case (and I’ve added a small conditional to only add 0.01 when the value is 0). Is there another workaround? One other thing I noticed is if I increase the delta to 0.0001 for example, the Wallacei charts become illegible as the graph axis reflects a large value: [wallacei graphs] Any advice would …

More recently i have been multiplying the fitness value with -1 to maximise it instead of 1/x to bypass this problem.
