I'm curious about something. Supposed the cuckoo search can be use as an optimization technique which means we can either find the maximum or the minimum.

but after I tested it with several objective functions, i found that we have to know the tolerance in order to find the best solutions. which mean i have to know what gives the maximum or minimum value for the function.

supposed the cuckoo search have to find what the max or min value isn't it.?

but what i found, when I change the tolerance, the min value will be change which mean, the min value depends on the tolerance.

so, that mean this cuckoo search didn't find the minimum value, instead we have to know what is the value of tolerance to give the minimum value. isn't it?

can you explain about this? i'm really confuse about this matter.

hi..can someone help me..I want to use this cuckoo search algorithm to test a function. It state that we can change the function with our own function. But I don't know how and which part should I change. I want to test this function :
y=6x-x^2

can someone help me to get the value of x and y at maximum point.. thank you..
