Auto2Fit

- Version 1.0

Auto2Fit is a robust, flexible, easiest-to-use
regression, curve fit, global optimization, equation
solving and parameter estimation program by using
Evolution Algorithms (EAs). It is especially useful
for the complicated jobs that are hard or impossible
to be solved by regular/traditional approaches.

Application Areas:
Auto2Fit can be used in the areas such as:
1. Regression and Curve Fit: linear, nonlinear,
multi-nonlinear with no limitations on variable and
parameter number
2. Global Optimization: find the
maximal/minimal value of any function. The function
may be nonlinear, non-continues, non derivable.
3. Equation Solve: solve any type of equation
or system equations, both linear and nonlinear
4. Model Auto-calibration: parameter estimation
of complicated engineering model

Algorithms:
Four types of EAs as well as many of their
improved/modified versions and new schemes have been
implemented in Auto2Fit. It therefore provides plenty
of choices for end users to meet various problems.
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)
4. Maximum Inherit Optimization (MIO): four
schemes

More Features:
1. The script engine used in Auto2Fit is
extremely fast, for example, 5 - 30 times faster than
VB
2. Multi-data file, multi-outputs supported:
this unique feature makes it very useful for parameter
estimation with multi-data file.
3. Easy to handle file-depended parameters and
file-depended constants
4. Excel-like, multi-windows spreadsheet
embedded for easy pre- and post-data process
5. Over 100 examples are included in the
package, covering the areas of regression, curve fit,
optimization, equation solving and parameter
estimations
