P vs NPTuring machinecomputation timequantum computerquantum computer as a Turing machine generalizationThe CMI Millennium "P vs NP Problem" can be resolved e.g. if one shows at least one counterexample to the "P = NP" conjecture. A certain class of prob...
Are you familiar with the concept of computational complexity? The P vs. NP enigma is crucial here. But what does it have to do with Tetris? Read the blog to find out.
The “P” in P versus NP stands for polynomial time. That just means we can predict the maximum amount of time it will take to solve the problem. You may have never heard of P versus NP, but in this article, Zack Grossbart will walk you through it, show you how it works and expla...
This definition is a bit hard to swallow, but examples clarify the situation greatly. For the problem of graph coloring, we note that a certificate would simply be a list of pairs $ (v_i, n_i)$ which give a coloring of the graph $ G$. It is quite trivial to define a polynomial-...
I will conclude with a few non computational problems, which capture ${\cal P}$ vs. ${\cal{NP}}$ and related computational complexity problems, hopefully inviting more mathematicians to attack them as well. I believe it is important to give many examples, and to underlie the intuition (...
P vs. NP P: Set of all decision problems that can be solved in polynomial time. NP: Set of all decision problems that can be verified in polynomial time. Any problem in P is also in NP. Are there problems in NP that are not in P? The answer is not known! NP-Complete problems:...
MPICH Release %VERSION% MPICH is a high-performance and widely portable implementation of the MPI-4.1 standard from the Argonne National Laboratory. This release has all MPI 4.1 functions and features required by the standard with the exception of support for user-defined data representations for I...

In this article, we will learn about the p-value, its significance and its uses in statistical analysis and tables with solved examples. Check out this article onArithmetic Mean. P-value A statistical measurement known as a p-value is employed to check a hypothesis’ validity against actual ...
This subject can be pretty difficult, as each DP soluble problem must be defined as a recursion relation, and coming up with it can be tricky. I suggest looking at many examples of DP problems until you have a solid understanding of the pattern involved. Videos: the Skiena videos can be...
