# P≟NP

I don’t have a solution for P≟NP, but I may have some insight as to what direction we can take to arrive at a solution.

My theory is that there are certain concepts and shortcuts in our mathematical/computational language that hide what we’re really doing on an absolute level.

An example would be working with numbers. Essentially a number is a sequence of elements (or if it’s a real number, two sequences—one before the decimal point and one after; if it’s a complex number, 4 sequences). The simplest way to qualify the range of the sequences would be to use base 2 and consider the range to be {0, 1}, but you can use any base you want.

A number is not just a sequence, though; certain sequences being “numbers” implies certain relationships between them and the possible operations on them. If, instead of “*”, we listed the algorithm applied to the sequences involved that multiplication reduces to, we would be using a language that more directly reflects what we’re actually doing.

I think that finding a language that wholly reflects what we’re actually doing when we compute—and not because it’s possible to directly reflect what you’re actually doing in the language but because it’s necessary to—would be the first stepping stone in solving P≟NP.

I think of particular importance would be how we define selecting a limited amount of members from a larger set. An analogy would be the difference between procedural programming and constraint programming; or maybe between constraint programming and something like functional programming except where the executor doesn’t do any sophisticated things to figure out how to solve problems; or maybe between regular functional programming, where the executor is sophisticated, and a kind of limited functional programming, where you have to spell out how to do anything sophisticated/combinatorial/quadratic/whatever within the code.

So, for example, when defining prime numbers in this new mathematical language, the very act of defining them would necessitate implementing some kind of algorithm for selecting them.

But then, you’d think that if it’s necessary to define an algorithm for selecting the primes just by the nature of the definitional language, then it wouldn’t be arbitrary which algorithm you select, yet there is definitely more than one possible algorithm to implement. Maybe the reconciliation of those two facts is that this new language would make it obvious how all solutions that select primes (at least from the same range, be it finite or infinite) are equal or isomorphic to each other. And if it can do that, then it wouldn’t be too far a leap to expect it to make it obvious, for our purpose of proving P≟NP, how the solution to any NP-complete problem leads to the solution to any other NP-complete problem.

Not that this gets you all the way to solving P≟NP, but the point is that once you have this language, you’re way closer to the essence of all problems and solutions, which should naturally lead to insights into solving P≟NP. It might still be a lot of work, but at least we’d have a starting point, whereas it seems that currently we’re clueless as to where to even start.
