The gtkdataboxmm C++ binding provides a C++ interface on top of the gtkdatabox C library. GtkDatabox is a widget for live display of large amounts of fluctuating numerical data. Data presentation (e.g. on linear or logarithmic scales, as dots or lines, with markers/labels) as well as user interaction (e.g. measuring distances) is easy. (see https://sourceforge.net/projects/gtkdatabox/ )

Lep-MAP
fast and accurate linkage map construction for large SNP datasets
Lep-MAP is a novel linkage map construction software. Note there is a new version, Lep-MAP2 available in https://sourceforge.net/projects/lepmap2/ Also note a bug in Lep-MAP: genotype alleles should be given in numerical order like "1 2", not as "2 1". If you use Lep-MAP, please cite Lep-MAP: fast and accurate linkage map construction for large SNP datasets Pasi Rastas; Lars Paulin; Ilkka Hanski; Rainer Lehtonen; Petri Auvinen Bioinformatics 2013; doi: 10.1093/bioinformatics/btt563 -

EmulMultiFit
Simultaneously fit SAS data with polydisperse core-shell-shell spheres
Keywords: -simultaneously fit several SAXS and SANS data sets with polydisperse (Schultz-Zimm or Gaussian distribution f(R)) spherical core-shell-shell nanoparticles -analytical expressions are used for from factor F(Q) and its integral over f(R), no numerical integration required -absolute units -Mathematica is required via console (MathKernel) -Mathematica's local and global optimizers (simulated annealing, differential evolution, Nelder-Mead, ...) can be used -range for fit parameters and further constraints between fit parameters are possible -Monodisperse(!) hard sphere structure factor can be used, too -long computation times (depending on problem size and amount of constraints) from hours to a few days are possible -non-parallelized code -

ExactCalc
Software for exact computing based on interval arithmetic.
...Simply speaking, because 1/3 is in interval [0.33, 0.34] and 1/7 is in interval [0.14, 0.15], value 1/3 - 1/7 must be in [0.18, 0.2]. Computation can be arbitrary long and complex but interval arithmetic gives interval that contains exact result of computation. Sometimes is more easy to use numerical unstable algorithm to solve problem. Instability is actually speed of accumulating the truncation error, but it can be decreased arbitrary by using more precise computation. Interval arithmetic provides us control of accumulating truncating error. To save Your time using CPU time this program provides interpreter of simple programming language based on interval algebra with arbitrary precision arithmetic. -

PyGAO
Genetic Algorithm Optimization for Python
A simple interface for performing genetic algorithm optimization for numerical problems. I am starting with a stripped-down version, where a solution can be described using a single vector of float numbers. Eventually, I will expand to more generic data structures and add multiple-species search options. For the time being, I have no plans of developing a GUI. For now, this is strictly a computational module. -

Runge
Runge is an Interactive Solver for Systems of Differential Equations
...It uses Runge Rule to adjust step length to satisfy required precision on each step. It's effective. When it needs to compute derivatives (Jacobian matrix, for example) it does that analytically, i.e. without using numerical methods. It's portable. It works on Windows and Linux 32 and 64 bit and Mac OS X 64 bit. It's open. It allows you to implement and embed your own algorithms (aka "solvers"). It's easy to use. It allows to export results to MS Excel and MATLAB. It's multilingual. It currently supports Englis and Russian languages. ... -

Z spatial correction
A PERL script to perform spatial corrections on plate scores.
...The first column heading must be the word "plate" (case not important), otherwise the heading won't be recognised There can be any number of plates, and each plate can have any number of rows and columns. Columns are numerical, where as rows are letters (A, B, C etc) The script adjusts the scores (assumed to be Z scores) based upon column and row averages relative to the median plate value The scores should be numerical not text, although the script makes some attempt to parse out text from the scores -
