seidel

Seidel is a surname of German origin. It is found in German-speaking countries and communities abroad, with several orthographic variants including Seidl and Seydel.

Notable individuals bearing the name include Raimund Seidel, a computer scientist recognized for contributions to computational geometry and randomized algorithms. He is best known for introducing what are now called Seidel’s algorithms, a class of randomized incremental methods applicable to problems such as convex hull construction and linear programming in fixed dimensions.

In geometry and theoretical computer science, Seidel’s algorithm refers to these randomized incremental approaches that solve certain geometric and optimization problems efficiently in low dimensions. The methods are characterized by their probabilistic analysis and expected time performance, which make them a foundational reference in discussions of practical geometric computation and algorithm design.

The Seidel surname has appeared in various other fields through individuals who contribute to academia, engineering, the arts, and public life. As a family name, Seidel illustrates the range of Germanic-origin surnames that have spread internationally over time.
