Discussion of Problem 1766. Humpty Dumpty

WA 16
Posted by Zefick 1 Jun 2010 12:06
I solve the system by the Gauss method, but the 16-th test he passes.
Then I tried to take first the Gauss method and the results of the initial matrix method of Seidel (iterative algorithm), but it does not always converge and the result becomes invalid even before the 16-second test.
What is there a problem?
