ExReDi

The Extreme Resilient Discretization project (ExReDi) was established to address these challenges for algorithms common for fluid and plasma simulations.

In a highly cyclic community (S3), vertices in each subgroup mostly connect directionally to vertices in the “next” adjacent subgroup. The new factorizations enable discovery of such phenomena.

Math for Data Mining

Newly developed mathematical techniques reveal important tools for data mining analysis.
