Hi, first of all you have to keep hands off i if you handle complex numbers. Don't use it as iterator variable. Second, I am not sure what for(4) actually does. Unfortunately I can't break down it to a minimum working example. The disabled region should work as the for(3) loop with exit condition but it doesn't (somehow gets stuck). Tests with trace showed that inside the for(4) loop the arithmetics seem to be rotten. For comparison I added a loop-free implementation of the algorithm by just repeating the commands in the sheet. Once one accepts the complex numbers, the algorithm converges to a reasonable solution. Yet, the radius turns out negative for the given initial guess. This can happen because only the square of the radius occures in the model. ![2024-02-17 15_01_08-SMath Solver - [Triangle-Circle-Newton_kr.sm_].png](/forum/resource.ashx?a=49008&b=2)  Triangle-Circle-Newton_kr.sm (195kb) downloaded 5 time(s). |

I don't think you've actually adopted the KISS principle here Valery! The attached seems much simpler. Triangle-Circle-Newton_stvmath.sm (117kb) downloaded 17 time(s).
