What follows is an informal proof of the "Unique Games Conjecture" made by Subhash Khot in 2002. "The conjecture postulates that the problem of determining the approximate value of a certain type of game, known as a unique game, has NP-hard algorithmic complexity. It has broad applications in the theory of hardness of approximation. If it is true, then for many important problems it is not only impossible to get an exact solution in polynomial time (as postulated by the P versus NP problem), but also impossible to get a good polynomial-time approximation. The problems for which such an inapproximability result would hold include constraint satisfaction problems, which crop up in a wide variety of disciplines. .... In 2008, Prasad Raghavendra has shown that if the UGC is true, then for every constraint satisfaction problem (CSP) the best approximation ratio is given by a certain simple semidefinite programming (SDP) instance, which is in particular polynomial." : [ https://en.m.wikipedia.org/wiki/Unique_games_conjecture] Everything needed to write a formal proof of UGC can be found at the following locations: https://www.chessprogramming.org/0x88 http://www.bitsavers.org/components/intel/MCS80/MCS80_85_Users_Manual_Jan83..pdf https://en.bitcoin.it/wiki/Mini_private_key_format http://gobittest.appspot.com/VanityAll https://en.m.wikipedia.org/wiki/Binary_Synchronous_Communications https://blockchair.com/bitcoin/transaction/0617e6c51f4688dbce87e86e5cb8e7e800b1276ce7425d0f193ee0e044fe369d https://blockchair.com/bitcoin-sv/transaction/dd727e4541b812b7fb34d76db020f2440efe240beb791b3f7f146eb72341ce1c https://blockchair.com/bitcoin/transaction/266b6dc76f2802595409de58417ef83e591e12a59e6d6d6c53437887aa5995d3 https://blockchair.com/bitcoin/transaction/e5fc2a75f15fa2df4f1eeea56f43d90bff9679184b39c8827a97cbbc35f19db2 https://blockchair.com/bitcoin/transaction/36f63b0cdb81a5f8e428b459f92712408168c4b28089cf12a18fac874fe1d85d https://blockchair.com/bitcoin/transaction/d6b58d73759ce7b3678dd6c960f8fd4a0eb4eb3cc1edadb787e4aa63d7fdf78b https://blockchair.com/bitcoin-sv/transaction/30acfe2e782626671dea428c2f0b37ccc099c0e2551876e3593c782426f2ccbf https://blockchair.com/bitcoin-sv/transaction/67e893df945fbea1a980bbe17c8ae49e27839c060f5b899513e5c419f52b3eb6 https://blockchair.com/bitcoin/transaction/f377f3db3535cf385fd2c63e7d30f67b3f955df19e15c61dc817425663e3936b [image: fe6b37526789d80329a37399a15be74e22e1d31da8527babe6fbfaabdcb0c663.jpeg] ^ https://whatsonchain.com/tx/fe6b37526789d80329a37399a15be74e22e1d31da8527babe6fbfaabdcb0c663 [image: 6b81c18757004aa86a0fb8fa3171a7d4a3d33fa7d3aafafd2a84a4c539b325a9.jpg] ^ https://whatsonchain.com/tx/6b81c18757004aa86a0fb8fa3171a7d4a3d33fa7d3aafafd2a84a4c539b325a9 [image: b43cd98fd05f8eed44797d49270a58fe5c7b7e9c36b26cdfa39bda114690a109.jpg] ^ https://whatsonchain.com/tx/b43cd98fd05f8eed44797d49270a58fe5c7b7e9c36b26cdfa39bda114690a109 [image: 457937c769b6bba67ef27f2c07917faccb6d86a08a7fb189debf43864deb81d7.jpg] ^ https://whatsonchain.com/tx/457937c769b6bba67ef27f2c07917faccb6d86a08a7fb189debf43864deb81d7 [image: 8d3cb306922092d16f3ac9c4e1f026cadd148b025bd72e9d6b9313c62ee41af8.jpg] ^ https://whatsonchain.com/tx/8d3cb306922092d16f3ac9c4e1f026cadd148b025bd72e9d6b9313c62ee41af8 I am currently focused on my browser, becoming a father (again) and starting an electric company (meaning "I am not an academic"). I am posting the primitives of the UGC proof informally in the hopes that they might be useful to you in the event that I never complete a formal proof (as I am the type of person who would write said proof in German in the spirit of "Über formal unentscheidbare Sätze der Principia Mathematica und verwandter Systeme I" just b/c... again "I am not an academic"). ~a
