Symmetry groups of Cephoids : part 1 ; Square Cephoids

Rosenmüller, Joachim - 2026

We continue the analysis of Cephoids. A Cephoid is a Minkowski sum of finitely many standardized simplices ("deGua simplices''). Pareto faces of a Cephoid are maximal polyhedra facing "outward''. A Pareto face consists of an algebraic sum of subsimplices of the deGua Simplices involved, the...

A stochastic nonlinear programming model for budget mix optimization of digital marketing campaigns under uncertainty

Yahia, Zakaria; ElBolok, Mostafa - In: Future business journal 11 (2025) 1, pp. 1-28

This study introduces a stochastic mixed-integer nonlinear programming (MINLP) model designed to optimize budget allocation for digital marketing campaigns under uncertainty. The model maximizes Expected Net Reach (ENR) by integrating the Sainsbury Normal Method (SNM) to correct for audience...
