Column-generation for a two-dimensional multi-criteria bin-packing problem
In this study, we examine a two-dimensional bin-packing problem in printed circuit board manufacturing. Among other objectives, the number of bins, but also the number of different bin layouts, is to be minimized. As the running times of an earlier MIP presentation are only acceptable for small problem instances, we will now discuss a branch-and-price approach by using an adapted Ryan-Foster-branching. The pricing problem computes the layouts, separating the time-consuming constraints from the …

Experiences with Model Context Protocol Servers for Science and High Performance Computing
Large language model (LLM)-powered agents are increasingly used to plan and execute scientific workflows, yet most research cyberinfrastructure (CI) exposes heterogeneous APIs and implements security models that present barriers for use by agents. We report on our experience using the Model Context Protocol (MCP) as a unifying interface that makes research capabilities discoverable, invokable, and composable. Our approach is pragmatic: we implement thin MCP servers over mature services, includi…
