This is what i have seen "P appears to be equal to NP". To view the computer program (subset sum problem) and the publication please go to website: fofallthings. Open with internet explorer.
Given a set of integers. For instance, {-2, -3, 15, 14, 7, -10} does some nonempty subset of them sum to 0? The computer program gives answer: "yes, because {-2, -3, -10, 15} adds up to zero"
(BTW, edited) P appears to be equal to NP before the complexity of the problem grows.
However, it was later proven that P ≠ NP.
