Options Changes in R2016a

Use `optimoptions` to Set Options

Before R2016a, you set options for some Global Optimization Toolbox solvers by using a dedicated option function:

gaoptimset for ga and gamultiobj
psoptimset for patternsearch
saoptimset for simulannealbnd

Beginning in R2016a, the recommended way to set options is to use optimoptions. (You already set particleswarm options using optimoptions.)

Note

GlobalSearch and MultiStart use a different mechanism for setting properties. See GlobalSearch and MultiStart Properties (Options). Some of these property names changed as solver option names changed.

Some option names changed in R2016a. See Table of Option Names in Legacy Order.

optimoptions “hides” some options, meaning it does not display their values. optimoptions displays only current names, not legacy names. For details, see View Optimization Options.

Options that `optimoptions` Hides

optimoptions does not display some options. To view the setting of any such “hidden” option, use dot notation. For details, see View Optimization Options. These options are listed in italics in the options tables in the function reference pages.

Options that optimoptions Hides

Option	Description	Solvers	Reason for Hiding
Cache	With `Cache` set to `'on'`, `patternsearch` keeps a history of the mesh points it polls. At subsequent iterations, `patternsearch` does not poll points close to those it already polled. Use this option if `patternsearch` runs slowly while computing the objective function. If the objective function is stochastic, do not use this option.	`patternsearch`	Works poorly
CacheSize	Size of the history.	`patternsearch`	Works poorly
CacheTol	Largest distance from the current mesh point to any point in the history in order for `patternsearch` to avoid polling the current point. Use if `'Cache'` option is set to `'on'`.	`patternsearch`	Works poorly
DisplayInterval	Interval for iterative display. The iterative display prints one line for every `DisplayInterval` iterations.	`particleswarm`, `simulannealbnd`	Not generally useful
FunValCheck	Check whether objective function and constraints values are valid. `'on'` displays an error when the objective function or constraints return a value that is complex, `Inf`, or `NaN`.	`particleswarm`	Not generally useful
HybridInterval	Interval (if not `'end'` or `'never'`) at which `HybridFcn` is called.	`simulannealbnd`	Not generally useful
InitialPenalty	Initial value of penalty parameter.	`ga`, `patternsearch`	Difficult to know how to set
MaxMeshSize	Maximum mesh size used in a poll or search step.	`patternsearch`	Not generally useful
MeshRotate	Rotate the pattern before declaring a point to be optimum.	`patternsearch`	Default value is best
MigrationDirection	Direction of migration — see Migration Options.	`ga`	Not useful
MigrationFraction	Scalar between 0 and 1 specifying the fraction of individuals in each subpopulation that migrates to a different subpopulation — see Migration Options.	`ga`	Not useful
MigrationInterval	Positive integer specifying the number of generations that take place between migrations of individuals between subpopulations — see Migration Options	`ga`	Not useful
PenaltyFactor	Penalty update parameter.	`ga`, `patternsearch`	Difficult to know how to set
PlotInterval	Positive integer specifying the number of generations between consecutive calls to the plot functions.	`ga`, `patternsearch`, `simulannealbnd`	Not useful
StallTest	String describing the stopping test.	`ga`	Default value is best
TolBind	Binding tolerance. See Constraint Parameters.	`patternsearch`	Default value is usually best

Table of Option Names in Legacy Order

These two tables have identical information. One is in alphabetical order by legacy option name, the other is in order by current option name. The tables show values only when the values differ between legacy and current, and show only the names that differ. For changes in Optimization Toolbox™ solvers, see Current and Legacy Option Names.

* indicates GlobalSearch and MultiStart property names as well as solver option names.
