And what is the meaning of calculating K? As soon as you increase the number of kangaroos, your K will fly into space.
With 65536 kangaroos in the classic version K will be 3.07
And when using the GPU, K increases even more due to dp overhead, in this case you will easily reach k=10
Correct, if you set a large number of kangaroos, DP overhead will be high and K will be high.
The number of kangaroos must be small related to sqrt(range), for example, it's a bad idea to use 64K kangaroos to solve 32bit range because total number of jumps of all kangs to solve 32bit is about 64K so it's just one jump for every kang, and DP>0 will cause a big overhead.
On GPU you have a lot of kangs but you will solve high ranges so K will be good.
There are many ways to get high K, you can play with parameters and find out how to keep it small.
The reason to calculate K is to see what parameters are the best.
