Description

I am selling my first car, which I have been driving for 27 years. The price will be reduced to 1 zł (one zloty) for the person who solves a mathematical problem: inverting the VMPC function that I discovered (my name is Bartosz Żółtak). This is the first one-way function in the world. If I manage to complete a proof of its one-wayness, it will solve the famous mathematical problem P vs NP, one of the seven Millennium Problems of the Clay Mathematics Institute. I published the function in 2004 at the international scientific conference FSE 2004. I have been doing research for 27 years. It is already close to completion. One month after discovering the function, in January 1999, I bought this Toyota, which I have been driving to this day. The funds raised are intended to help finance the final stage of this research. I conduct it independently and finance it with the help of people of goodwill: www.zrzutka.pl/vmpc The car is in working order, it has a current inspection and insurance (OC), but it requires some investment. Due to a limited repair budget, I carried out the bodywork myself using polyester resin with fiberglass, and the car has been painted with a sponge roller using rust paint. The car is a member of Toyota’s Club for Record Mileages, with a gold badge. The engine runs well and does not consume oil. All rigid brake lines have been replaced with copper ones (so there is no concern about corrosion). The car has a new Yuasa battery. The suspension and steering system have no play. A few wear-and-tear parts need replacement. I am adding a set of 4 extra wheels (steel rims identical to those in the photos with winter tires) and some spare parts. Here are the details of the mathematical task: You need to find a 100-element permutation f for which the value of the VMPC function is: (57, 40, 75, 22, 90, 67, 58, 47, 93, 74, 83, 72, 17, 97, 51, 59, 39, 60, 78, 16, 44, 61, 18, 98, 34, 96, 14, 21, 88, 56, 77, 66************* 7, 2, 19, 94, 12, 15, 92, 70, 49, 1, 5, 38, 84, 63, 82, 50, 20, 79, 13, 29, 76, 42, 25, 48, 33, 35, 68, 24, 99, 11, 27, 10, 71, 8, 31, 43, 85, 53, 36, 6, 9, 81, 64, 0, 80, 45*************89, 41, 54, 62, 28, 26, 65, 91, 86, 87, 55, 73*************69) For every x from 0 to 99, the above values of the VMPC function are given, defined by the formula f(f(f(x))+1), where + means addition modulo 100. So we have: f(f(f(0))+1)=57, f(f(f(1))+1)=40, f(f(f(2))+1)=75, …, f(f(f(99))+1)=69. You need to find 100 elements of the permutation f. To make it easier, I provide the first two elements of the correct solution: f(0)=45, f(1)=88. The solution will be announced in the news section on the website devoted to research on the VMPC function: www.pieknafunkcja.pl
