Auto2Fit is a revolution tools and beats all other simliar ones in the area of nonlinear regression! Almost all data analysis software packages (SPSS, SAS, Statistical,Origin Pro, DataFit, Stata or Systat) need end-users to provide/guess initial start values, and the successes of nonlinear regression computation are havily depended on those guessed data. Unfortunately, for most of people, the guesses of proper start values are nightmare. With the unique, robust and high efficient optimation algorithms of "Global Levenberg-Marquardt" and "Global BFGS", proposed newly, Auto2Fit is no long to require the end-users to provide/guess initial start values (but with free random ones), the performance, however, is much better than any others. Auto2Fit has turned to be the best one for nonlinear regerssion analysis nowadays. Auto2Fit is also a flexible, versatile, easiest-to-use tool in the areas of function optimization, equation solving, parameter estimation, combinational problems (like TSP) and chart drawing. Algorithms: A number of optimization algorithms have been integrated in Auto2Fit: 1. Genetic Algorithm (GA): both encode/decode mode and real-value based mode, six crossover types and seven selection types 2. Particle Swarm Optimization (PSO): six schemes (2 standard and 4 new) 3. Differential Evolution (DE): ten schemes (5 new) and four routs (3 new) 4. Maximum Inherit Optimization (MIO): four schemes 5. Simulated Annealing (SA) 6. Simplex Method (SM) 7. Levenberg-Marquardt (LM): standard LM and Global LM 8. Quasi-Newton (BFGS): standard BFGS and Global BFGS 9. Self-Organizing Migrating Algorithms (SOMA) 10. Conjugate-Gradient Method (CGM) 11. Powell Optimization (OP) 12 Tabu Search (TS)

Mathaid interactive Probability and Statistics tutorial is a new java-based package for e-learning and home schooling. It guides the user through all steps of the learning process, from theoretical concepts, examples, problem-solving lessons, drills to customized tests including solutions and evaluation. The emphasis is on interactivity and "living" formulas - the unique graphics and animations bring life to the formulas and make learning and exploring maths real fun. Topics covered: counting principles and probability, random variables, discrete distributions, continuous distributions, distributions related to the normal, parameter estimation, hypothesis testing, linear regression. The demo version contains selected lessons from the full version, fully functional, all features included.

IP Shifter is a smart software tool that helps you to change your TCP/IP related settings easily and quickly. If you work dynamically at several locations in the network (due to business), you need to be connected in different offices, or you need to use your computer in more than one network, in these cases, you have to change your IP address parameters (e.g. IP address, Subnet mask, Gateway, DNS, Proxy) frequently, so IP Shifter is a product for you! It can help you to finish this activity. It can handle multiple network adapters! That means that each configuration could be defined for the specific adapter and you can choose any of the currently enabled adapters. You do not need to reboot your PC every time after applying of the selected configuration. your new configuration will be active in the system instantly.
