Theorem Prover

IsaMorph is a linux distribution Live CD (based on Morphix) featuring the interactive theorem prover Isabelle. This means, you can boot from the CD and get a fully operational "theorem proving" environment without installing GNU/Linux or Isabelle. Just insert the CD in your PC and have five...

Spassgui is a Perl/Tk based Gui for SPASS (An Automated Theorem Prover for First-Order Logic with Equality) by http://spass.mpi-sb.mpg.de .

The Archive of Formal Proofs is a collection of proof libraries, examples, and larger scientifc developments, mechanically checked in the theorem prover Isabelle. It is organized in the way of a scientific journal. Submissions are refereed.

VCC is a mechanical verifier for concurrent C programs. VCC takes a C program, annotated with function specifications, data invariants, loop invariants, and ghost code, and tries to prove these annotations correct. If it succeeds, VCC promises that your program actually meets its specifications....

The Gaussian Kernel can be changed to any desired kernel. However such a change will not dramatically improve results. This is a variant of ridge regression using the kernel trick (Mercers Theorem).

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....

The program shows how to plot figure 14.4 page 248 presented in T. L. Hill, An Introduction to Statistical Thermodynamics, Dover, New York, 1986. The Bragg-Williams approximation gives pressure-volume isotherms similar to those obtained using the van der Waals equation and it predicts first-order...

The harmony elements algorithm is proposed as a global searching technique of numerical computing which inspired by the old Chinese philosophy: Doctrine of Wu Xing, the five color theorem, and the Hoffman-Singleton graph. According to operation of overcoming and generating policy, each element in...
