Constructor & Destructor Documentation

FloatTestEAEnv (  const StringMap &    params, int    dim = 2, int    funct_b = -1 )

Standard constructor. Parameters: params  Dynamic parameters in a String Map. Important only for defining ["BitFloatGene.grayCoding"]. dim  Dimension of the search space, i.e. number of floating-point genes in the genome. Genes will gave value range [-4,4]. BitFloatGenes will have 16 bits. funct_b  ? Definition at line 95 of file testenv.cc. References dim, and func.

Member Function Documentation

void addFeaturesTo (  Genome &    genome )  const [virtual]

Adds problem-specific features to a genome. Reimplemented from EAEnvironment. Definition at line 102 of file testenv.cc. References Gentainer::add(), and dim.

double calc (  const Vector &    v, int    f )

Calculates the value of test function with given input vector. Parameters: v  Parameter vector. f  ID of test function. Definition at line 201 of file testenv.cc. References func. Referenced by evaluateg(), and printMathematica2D().

void changeObjective (  int    o )  [inline]

Changes the objective. Definition at line 110 of file testenv.h.

virtual void cycle_report (  OStream &    log, OStream &    out )  [inline, virtual]

Prints some statistics or something at the end of the evaluation cycle. Reimplemented from EAEnvironment. Definition at line 122 of file testenv.h.

double evaluateg (  const Individual &    indiv )  [virtual]

Evaluates the fitness of the given individual in the environment. MUST OVERLOAD! Exceptions: must_overload  Reimplemented from EAEnvironment. Definition at line 193 of file testenv.cc. References calc(), dim, func, and Individual::getGene().

virtual void init_cycle (    )  [inline, virtual]

Initializes a generation. Not necessary in all models. Reimplemented from EAEnvironment. Definition at line 120 of file testenv.h.

void printMathematica2D (    )

Makes an extensive search of all search spaces (functions) in two dimensions. The output is printed as Mathematica matrices. Definition at line 226 of file testenv.cc. References calc().

void setGeneType (  int    vt )  [inline]

Sets the gene type: name ESFLOAT is FloatGene and name BITFLOAT is BitFloatGene (with 16 bits). Definition at line 115 of file testenv.h.
