An MM Algorithm for Split Feasibility Problems
Jason Xu, Eric C. Chi, Meng Yang +1
The classical multi-set split feasibility problem seeks a point in the intersection of finitely many closed convex domain constraints, whose image under a linear mapping also lies…
Distance Majorization and Its Applications
Eric C. Chi, Hua Zhou, Kenneth Lange
The problem of minimizing a continuously differentiable convex function over an intersection of closed convex sets is ubiquitous in applied mathematics. It is particularly interest…
Techniques for Solving Sudoku Puzzles
Eric C. Chi, Kenneth Lange
Solving Sudoku puzzles is one of the most popular pastimes in the world. Puzzles range in difficulty from easy to very challenging; the hardest puzzles tend to have the most empty…
A Look at the Generalized Heron Problem through the Lens of Majorization-Minimization
Eric C. Chi, Kenneth Lange
In a recent issue of this journal, Mordukhovich et al.\ pose and solve an interesting non-differentiable generalization of the Heron problem in the framework of modern convex analy…
