3D objects (3DO) Bitmap (BMP) Boundary (BND) Directive (DIR) Domain (DOM) Expansion (EXP) Field (FLD) Field formula (FLF) Field transform (FLT) Function (FUN) General information Grid formula (GRF) Grid transform (GRT) Integral (INT) MMP (MMP) Movie (AVI) OpenGL (OGL) Palette (PAL) PET basis (BAS) PFD (PFD) Project (PRO) Window (WIN)
PET basis files contain the formula for the basis functions of the Parameter Estimation Technique (PET), a method to speed up series of MMP computations. For reasons of compatibility with GGP (Generalized Genetic Programming, an evolutionary optimization code available on the World Wide Web: http://alphard.ethz.ch), these files contain additional information that is not explicitly used in OpenMaXwell. Note that OpenMaXwell will replace the parameters of the formula by the corresponding values when it reads these files. OpenMaXwell evaluates the entire basis fitness. For more information on the GGP fitness definition, consult the web pages indicated above.
Data structure:
File ID string (Current version: " CHBAS Version 1.0")
Number of basis functions and fitness value of the entire basis (1 integer, 1 real value)
LOOP i=1, Number of basis functions
Basis function formula (character string)
Amplitude, parameter, fitness of the basis function (3 real values)
