Optimization and Real World Applications

Fixed Point Theory and Algorithms for Sciences and Engineering welcomes submissions to the Topical Collection on “Optimization and Real World Applications” edited by Heinz Bauschke (University of British Columbia, Canada), Yunier Bello-Cruz (Northern Illinois University, USA), Radu Ioan Bot (University of Vienna, Austria), Robert Csetnek (University of Vienna, Austria), and Alexander Zaslavski (Israel Institute of Technology, Israel), which covers a wide variety of topics concerning optimization problems and their applications. 

These include (but are not limited to) 
- smooth and nonsmooth optimization problems (theory and numerical methods), 
- monotone operators and nonexpansive mappings,
- real world applications in 
                    - machine learning,
                    - image/signal processing,
                    - data classification,
                    - scientific computing
and other areas.

TC Optimization and Real World Applications


  1. The circumcentered-reflection method (CRM) has been applied for solving convex feasibility problems. CRM iterates by computing a circumcenter upon a composition of reflections with respect to convex sets. Sinc...

  5. By the first welfare theorem, competitive market equilibria belong to the core and hence are Pareto optimal. Letting money be a commodity, this paper turns these two inclusions around. More precisely, by generali...

  7. Splitting algorithms for finding a zero of sum of operators often involve multiple steps which are referred to as forward or backward steps. Forward steps are the explicit use of the operators and backward ste...

  8. It is well known that the Newton method may not converge when the initial guess does not belong to a specific quadratic convergence region. We propose a family of new variants of the Newton method with the pot...

  11. We explore a new approach for training neural networks where all loss functions are replaced by hard constraints. The same approach is very successful in phase retrieval, where signals are reconstructed from m...
