About Project Euler Leonhard Euler (1707-1783)

What is Project Euler? Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to >solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be >required to solve most problems.>

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas >and learn new concepts in a fun and recreational context.>

Who are the problems aimed at? The intended audience include students for whom the basic curriculum is not feeding their hunger to learn, adults whose background was not >primarily mathematics but had an interest in things mathematical, and professionals who want to keep their problem solving and mathematics >on >the cutting edge.>

Can anyone solve the problems? The problems range in difficulty and for many the experience is inductive chain learning. That is, by solving one problem it will expose you to >a new concept that allows you to undertake a previously inaccessible problem. So the determined participant will slowly but surely work his/her >way through every problem.>
