In computational complexity theory and computability theory, a counting problem is a type of computational problem. If R is a search problem then. is the corresponding counting function and. denotes the corresponding decision problem. Note that cR is a search problem while # R is a decision problem, however cR can be C Cook-reduced to # R (for ...

List of unsolved problems in astronomy. This article is a list of notable unsolved problems in astronomy. Problems may be theoretical or experimental. Theoretical problems result from inability of current theories to explain observed phenomena or experimental results. Experimental problems result from inability to test or investigate a proposed ...
Using the CT markers of visceral fat, subcutaneous fat, muscle mass, liver density, and aortic calcium, researchers were able to determine a person’s type 2 diabetes risk. Scientists found that ...
Of the cleanly formulated Hilbert problems, numbers 3, 7, 10, 14, 17, 18, 19, and 20 have resolutions that are accepted by consensus of the mathematical community. Problems 1, 2, 5, 6, [g] 9, 11, 12, 15, 21, and 22 have solutions that have partial acceptance, but there exists some controversy as to whether they resolve the problems.

AlphaGeometry is an artificial intelligence (AI) program that can solve hard problems in Euclidean geometry.It was developed by DeepMind, a subsidiary of Google.The program solved 25 geometry problems out of 30 from the International Mathematical Olympiad (IMO) under competition time limits—a performance almost as good as the average human gold medallist.
Hilbert's Entscheidungsproblem. Type inference and type checking for the second-order lambda calculus (or equivalent). [ 1] Determining whether a first-order sentence in the logic of graphs can be realized by a finite undirected graph. [ 2] Trakhtenbrot's theorem - Finite satisfiability is undecidable.
