Mathematics Mon, 24 Jan 2022 10:00:03 ESTnews562240102Researcher develops new tool for understanding hard computational problems that appear intractableThe notion that some computational problems in math and computer science can be hard should come as no surprise. There is, in fact, an entire class of problems deemed impossible to solve algorithmically. Just below this class lie slightly "easier" problems that are less well-understood—and may be impossible, too.

The way it contains the minimal possible surface area is surprisingly efficient. This is not a trivial issue. Mathematicians have been looking for better ways to calculate minimal surfaces for hundreds of years. Recently, Computer Science and Engineering Department Assistant Professor Albert Chern, and postdoctoral researcher Stephanie Wang, added a new page to this book with their paper: Computing Minimal Surfaces with Differential Forms, which was recently published by ACM Transactions on Graphics.

Namely, how does the choice of the starting point affect where a system ends up? Some systems are easier to describe than others. A swinging pendulum, for example, will always land at the lowest point no matter where it starts.

Mathematics Thu, 04 Nov 2021 06:54:30 ESTnews555227668To probe an unexplored space of hard problems, researchers play the devil's advocateIn computer science, the graph coloring problem is a classic. Inspired by the map-coloring problem, it asks: Given a network of nodes connected by links, what's the minimum number of colors you need to color each node so that no links connect two of the same color? For small numbers of colors and links, looking for a solution is straightforward: Just try all possible combinations. But as links increase, the problem becomes more constrained—until, if there are too many links and not enough colors, no solution may exist at all.
