Very cool.
I did a lot of mucking around with Simulated Annealing and the Metropolis algorithm while in uni. Using it for tasks like fitting various sized files onto minimum numbers of floppy disks, finding optimum solutions for student + classroom + teacher timetables for schools etc.
But given the money to be made in the financial realm, I can't see these algorithms making it to the public domain any time soon.

Hi all. I was able to set up an IBM Ultrium LTO 4 tape drive to use iSCSI (using open-iscsi drivers) to communicate with Red Hat, but it's going really slow, maxing out in tar and dd tests at like 16 MB/s (using a block size of 128k). The thing is rated for 30MB/s. I feel like even though I have... (1 Reply)

The library covers the following areas,
Complex Numbers
Roots of Polynomials
Special Functions
Vectors and Matrices
Permutations
Combinations
Sorting
BLAS Support
Linear Algebra
Eigensystems
Fast Fourier Transforms
Quadrature
Random Numbers
Quasi-Random Sequences

Statistics
Histograms
N-Tuples
Monte Carlo Integration
Simulated Annealing
Differential Equations
Interpolation
Numerical Differentiation
Chebyshev Approximations
Series Acceleration
Discrete Hankel Transforms
Root-Finding
Minimization
Least-Squares Fitting
Physical Constants
IEEE Floating-Point
For more information please consult the GSL Reference Manual, which is available as an info file. You can read it online using the shell
command info gsl-ref (if the library is installed).
