Recently, I read that it is the first time that human finds 3 integers x, y and z which make x^3+y^3+z^3=33, where the finding is (8866128975287528)^3+(-8778405442862239)^3+(-2736111468807040)^3 in this March 2019. Till March 2019, we still can't find x, y and z for some numbers, for example, 42, 114, 165, 390, 579
Firstly I think we can make a three-variant-for-loop to find the answer. But obviously it is not a good solution. Maybe GPU can do better than CPU. Then I think some rules may be used: the end number of x^3 can be used to judge. But the if-else maybe takes more time then for-loop So, do you have any idea?
