Newton-like method with modification of the right-hand-side vector
This paper proposes a new Newton-like method which defines new iterates using a linear system with the same coefficient matrix in each iterate, while the correction is performed on...

An Agent Scheduling Optimization for Call Centers
A suitable assignment of agents to handle the workload at a call center is not easy to fulfill because it requires a combinatorial optimization with large solution space and the n...
