Journal of Optimization Theory and Applications

This special issue is devoted to presenting new developments in the fields of continuous optimization and variational analysis.
Contributions are expected, in particular, in the areas of convex and nonconvex optimization, nonsmooth optimization, minimax problems, quadratic programming, fractional programming, stochastic optimization, variational inequalities, equilibrium problems, vector and set-valued optimization, (splitting) proximal point type algorithms, (generalized) monotone operators, and equally welcome are investigations on concrete applications in economics, finance, engineering, computer sciences and machine learning, among others, that can be modeled as optimization problems (in the largest sense) and/or solved by means of numerical optimization. This special issue is related to the Chilean-Peruvian Conference on Optimization and Variational Analysis 2024 (ChiPOVA-2024).

This special Issue is in honour of the 10^th year anniversary of the Gaspard Monge Program in Optimization (PGMO) an industrially sponsored research program covering many different aspects of optimization theory. From an applicative viewpoint the program has, in particular, an interest in “energy related” problems. The latter, understood in a large sense, can be characterized by the presence of uncertainty, large scale, combinatorial aspects, nonsmoothness and non-convexity. The just mentioned features depending on the nature of the investigated models. Energy problems are of societal importance. As a result, the research in optimization carried out through PGMO can be understood to have real-life impact. In terms of mathematical optimization disciplines the scope of this SI is large as indeed a great many features can be found in problems from practice. We can thus cover:

• Stochastic programming
• Combinatorial optimization
• Nonsmooth and variational analysis
• Algorithmic developments
• Decomposition approaches
