General simulated annealing algorithm-anneal Minimizes a function with the method of simulated annealing (Kirkpatrick et al., 1983)　

　

ANNEAL takes three input parameters, in this order:　



LOSS is a function handle (anonymous function or inline) with a loss function, which may be of any type, and needn t be continuous. It does, however, need to return a single value.　

　

PARENT is a vector with initial guess parameters. You must input an initial guess.　

　

OPTIONS is a structure with settings for the simulated annealing. If no OPTIONS structure is provided, anneal uses a default structure. OPTIONS can contain any or all of the following fields (missing fields are filled with default values):　

　

　Verbosity: Controls output to the screen.　

　　0 suppresses all output　

　　1 gives final report only [default]　

　　2 gives temperature changes and final report　

　Generator: Generates a new solution from an old one. Any function handle that takes a solution as input and gives a valid solution (i.e.
