Source code:
(See also the source code section of Holding)
General:
pi.cc - various methods of approximating and calculating pi.
UpdatedSchulzeElection.tar.gz - Schulze Beat-Path election CGI scripts. Elects a condorcet winner, and if none exists, ranks basedon the shortest path among candidates on the condorcet matrix as a graph. [Update: Now works more true to the original Schulze paper]

Antenna optimizers:
helix.cc - bruteforce helix antenna diameter/length calculation
ttfd.cc - length calculation for tilted-terminated-folded-dipole (TTFD) antennas

Tools for cracking manual cryptography:
coincide.cc - performs frequency analysis, calculating Phi and index of coincidence as well.

Chaos plots (README):
plotter.h, plotter.cc - plotting classes required for most of the chaos plot programs
bifurcation.cc - Logistic/bifurcation map renderer.
lyapunov.cc - Plots "classical" lyapunov space (logistic equation with parameters osciallating between two values as given by x and y axis)
lyapunovhenon.cc - Plots Lyapunov space for the Henon attractor - numerical method, is not technically accurate.
techahenon.cc - Plots Lyapunov space for the Henon Attractor - more technically accurate numerical method, but slower than lyapunovehenon.cc. Compare output to see what is meant by "lyapunovhenon.cc is not technically accurate".
mandelbrot_preliminary.cc - Preliminary mandelbrot/mu molecule plotter. Greyscale.
mandelbrot.cc - Mandelbrot / mu molecule plotter. True-color.
boxcountdimension.cc - Calculates box-counting dimension for various combination of constants for arbitrary (programmed) strange attractors. Slow.
