Notes

The compact strategy stores a regularly spaced sub-sample where the minimum size of the stored numerical sample is . OpenTURNS proceeds as follows :

1. it stores the first simulations : the size of the stored sample is ,

2. it selects only 1 out of 2 of the stored simulations : then the size of the stored sample decreases to (this is the compact step),

3. it stores the next simulations when selecting 1 out of 2 of the next simulations : the size of the stored sample is ,

4. it selects only 1 out of 2 of the stored simulations : then the size of the stored sample decreases to ,

5. it stores the next simulations when selecting 1 out of 4 of the next simulations : the size of the stored sample is ,

6. then it keeps on until reaching the stopping criteria.

The stored numerical sample will have a size within and if at least one cycle has been done, else it will be at most .

__init__(*args)

clear()

Clear the stored points.

Notes

It erases the previously stored points

getClassName()

Accessor to the object’s name.

Returns:

class_namestr

The object class name (object.__class__.__name__).

getHalfMaximumSize()

Accessor to the half maximum number of points to store.

Returns:

Nint

The half maximum number of points to store.

getIndex()

Accessor to the index.

Returns:

indexint

The number of the stored points.

getName()

Accessor to the object’s name.

Returns:

namestr

The name of the object.

getSample()

Accessor to the stored sample.

Returns:

sampleSample

Numerical sample which is the collection of points stored by the history strategy.

hasName()

Test if the object is named.

Returns:

hasNamebool

True if the name is not empty.

setDimension(dimension)

Set the dimension of points to store.

This method must be called before calling the store method.

Parameters:

dimension: int

Dimension of points to store

Notes

It erases the previously stored points

setName(name)

Accessor to the object’s name.

Parameters:

namestr

The name of the object.

store(*args)

Store points or samples.

Parameters:

datasequence of float or 2-d sequence of float

Point or sample to store.

Notes

It adds a unique point or all the point of the sample in the natural order to the history.
