Ed has another paper on arxiv: using PDHG as a low accuracy LP solver inside branch-and-bound to get a primal heuristic for MIPs. arxiv.org/abs/2607.14483

Using a MIP Solver as a PDHG-Based MIP Heuristic

The PDHG algorithm provides a new capability for solving difficult linear programming (LP) problems: the ability to find low-accuracy solutions quickly. While such solutions may not be applicable in a...

What's next for GPU-accelerated optimization? We’ve seen how GPU-enabled algorithms can speed up solve times for some very large linear programs, but what does this mean for MIPs? https://ow.ly/5kNr50Y8uNX

Another article by Ed Rothberg on PDHG. arxiv.org/abs/2511.13894

Backing PDHG into a Corner

Recent enhancements to the Primal-Dual Hybrid Gradient (PDHG) algorithm have enabled GPUs to efficiently solve large linear programming problems, often faster than the long-dominant simplex and ...

Nice and short article by Ed Rothberg on concurrent crossover for PDHG (PDHG on GPU, crossover on CPU). arxiv.org/abs/2510.24429

Concurrent Crossover for PDHG

First-order methods based on the PDHG algorithm have recently emerged as a viable option for efficiently solving large-scale linear programming problems. One highly desirable property of these methods...
