Detailed Description

Inherited class for genetic optimization followed by a refinement with the method of gradient, one after the other. Parameters must be set for the two incapsulated optimizers genetic_opt and gradient_opt, that is for example: my_hybrid->genetic_opt->maxgenerations = 200; etc... However, the optimization variables, the system and the objective function must be added to the hybrid optimizer itself, which in turn will automatically set them for the genetic_opt and gradient_opt.

void chrono::ChOptimizerHybrid::SetObjective

(

char *

mformula

)

[virtual]

Sets the objective function to maximize, as ASCII interpreted formula Such fourmula will be interpreted by the "database" object.

Reimplemented from chrono::ChOptimizer.

void chrono::ChOptimizerHybrid::SetObjective

(

double(*)(double p[], void *my_data)

m_func

)

[virtual]

Set the C function which will be used for fx evaluation instead of parsing of "ascii" objective formula.

Reimplemented from chrono::ChOptimizer.

void chrono::ChOptimizerHybrid::SetNumOfVars

(

int

mv

)

[virtual]

Set the number of optimization variables. note: if you use the CHoptVar "ascii" variables, this is not needed -the count is automatic- but you MUST set it > 0 if you want to use the "C" evaluation of *funct()!!!

Reimplemented from chrono::ChOptimizer.

void chrono::ChOptimizerHybrid::SetDatabase

(

void *

newdb

)

Sets the database which will be accessed by interpreted formulas [obsolete].

Reimplemented from chrono::ChOptimizer.

void chrono::ChOptimizerHybrid::AddOptVar

(

CHoptVar *

newvar

)

[virtual]

Sets the optimization variables.

Reimplemented from chrono::ChOptimizer.
