New algorithm tackles complex fixed-charge network flow problems
Researchers have developed a new algorithm for the fixed-charge network flow problem (FCNFP), a complex optimization challenge that combines continuous flow allocation with discrete decisions. This novel approach, based…

New majorization analysis improves nuclear norm minimization convergence rates
This paper introduces a new majorization analysis for the smoothed nuclear norm, demonstrating that the harmonic-mean weight operator provides a valid global quadratic majorizer. The research establishes sharp convergen…
