How can cockroach reach the crump if it in circle he starting running along (I mean circle which center is closer to crumb). Can he go stright ahead and then go along the circle or he has to go along other circle firstly???
I' ve tried both variants.. but i have WA#13.

I've tried lots of variants of my solution... But if the optimal solution in this case is spiral, it gonna fail... BTW, here is approximately this very test after my normalization:

0 0 90 94.85
4.5 10.07

My answer is 605.5647, but it seems to be wrong

P.S. My geometry has always been unbeatable, so one day I will solve this problem ;)

It is realy wrong
Right one is 604.4120
