PathwayLab Research Edition is a Mathematica application package designed to analyze, visualize, and document biochemical pathways. PathwayLab Research Edition permits in ...

When nonlinear models are fitted to data it is important to make sure that the data is not overfitted. The reason for this is that many possible model structures, all with ...

A Sudoku can be regarded as a Constraint Satisfaction Problem with 27 All-Different constraints. Two methods of solving Sudoku are described. Both start by generating the ...

Constrained optimization problems arise naturally in many different disciplines. A structural engineer designing a multistory building must choose materials and proportions ...

The Mandelbrot set computation iterates until a certain distance exceeds two. Two is twice the distance of unity for complex numbers. Unity for B_3 numbers is B[{1,1,-2}]. ...

A fast method of modeling spectral lines is presented. The method utilizes a new approach in generating the Voigt profile using Mathematica. As an example, we consider the ...

Probability and its offspring, inferential statistics, constitute perhaps the most frustrating branch of human knowledge. The abstractness of formal methods scares many ...
