Multivalued forbidden numbers of two-rowed configurations -- the missing cases

The present paper considers extremal combinatorics questions in the language of matrices. An $s$-matrix is a matrix with entries in $\{0,1,\ldots, s-1\}$. An $s$-matrix is simple if it has no repeated columns. A matrix $F$ is a configuration in a matrix $A$, denoted $F\prec A$, i...

Minimizing cutting costs in 1D rod cutting

Abstract We study a one‐dimensional rod‐cutting problem arising from an industrial setting where cutting itself carries cost . Each order specifies a length interval, and the task is to assign orders to warehouse rods so that all orders are satisfied while the number of cuts is m...
