Traditionally, it was accepted that a relational database can be normalized step-by-step, from a set of un-normalized tables to tables in , then to , then to , then…
Iterative process of order 2 without inverting the derivative
Tamara Kogan, Luba Sapir, Amir Sapir +1
We prove the sufficient conditions for convergence of a certain iterative process of order 2 for solving nonlinear functional equations, which does not require inverting the deriva…
Nonstationary iterative processes
Luba Sapir, Tamara Kogan, Ariel Sapir +1
In this paper we present iterative methods of high efficiency by the criteria of J. F. Traub and A. M. Ostrowski. We define {\it s-nonstationary iterative processes} and prove that…
The Tower of Hanoi problem on Path_h graphs
Daniel Berend, Amir Sapir, Shay Solomon
The generalized Tower of Hanoi problem with h \ge 4 pegs is known to require a sub-exponentially fast growing number of moves in order to transfer a pile of n disks from one peg to…
