# reuse_points

This describes the behavior of reuse of points in constructing polynomial chaos expansion models.

Specification

- Alias: reuse_samples

- Arguments: None

- Default: no sample reuse in coefficient estimation

Description

The `reuse_points` option controls the reuse behavior of points for various types of polynomial chaos expansions, including: `collocation_points`, `collocation_ratio`, `expansion_samples`, or `orthogonal_least_interpolation`. If any of these approaches are specified to create a set of points for the polynomial chaos expansion, one can specify `reuse_points` so that any points that have been previously generated (for example, from the `import_points` file) can be reused.
