We present an algorithm for the solution of a simultaneous space-time discretization linear parabolic evolution equations with symmetric differential operator in space. Building on earlier work, we recast this into Schur-complement equation whose is quasi-optimal approximation to weak at hand. Choosing tensor-product discretization, arrive remarkably simple system. Using wavelets time and stand...

Nowadays, recommender systems are vital in lessening the information overload by filtering out unnecessary information, thus increasing comfort and quality of life. Matrix factorization (MF) is a well-known system algorithm that offers good results but requires certain level knowledge some effort on part user before use. In this article, we proposed an improvement using grammatical evolution (G...
