The minimum weight vertex cover problem (MWVCP) is well known combinatorial optimization problem that has several practical applications and formally defined as: Given an undirected graph with a set of vertices and edges, each vertex is assigned bya positive weight, the MWVCP aims to find a...

Beta-sorted portfolios - portfolios comprised of assets with similar covariation to selected risk factors - are a popular tool in empirical finance to analyze models of (conditional) expected returns. Despite their widespread use, little is known of their statistical properties in contrast to...
