Differential Item Functioning (DIF) is a powerful tool for developing fairer tests and mitigating bias in applicant selection tests. DIF aims to detect items in a test that favor or harm groups of people based on aspe...

In this paper, we consider a degree sum condition sufficient to imply the existence of k vertex-disjoint chorded cycles in a graph G. Let σ4(G) be the minimum degree sum of four independent vertices of G. We prove th...

The MUTLIAGENT PATH FINDING (MAPF) problem consists of identifying the trajectories that a set of agents should follow inside a given network in order to reach their desired destinations as soon as possible, but witho...
In real-life applications, many systems such as email, social websites and some financial organizations, use the password-based approach for user authentication. Thus, password strength plays a vital role in protectin...

Recurrent neural networks have flourished in many areas. Consequently, we can see new RNN cells being developed continuously, usually by creating or using gates in a new, original way. But what if we told you that gat...

A star-simple drawing of a graph is a drawing in which adjacent edges do not cross. In contrast, there is no restriction on the number of crossings between two independent edges. We forbid empty lenses, i.e., every le...
