`dynamic_rstar(size_t)` | The constructor.

###### dynamic_rstar(size_t)

The constructor.

Synopsis

    dynamic_rstar(size_t max_elements,
                  size_t min_elements = default,
                  size_t reinserted_elements = default,
                  size_t overlap_cost_threshold = 32)

Modifier(s)

Parameter(s)

Type | Name | Description
--- | --- | ---
`size_t` | `max_elements` | Maximum number of elements in nodes.
`size_t` | `min_elements` | Minimum number of elements in nodes. Default: 0.3*Max.
`size_t` | `reinserted_elements` | The number of elements reinserted by forced reinsertions algorithm. If 0 forced reinsertions are disabled. Maximum value is Max-Min+1. Greater values are truncated. Default: 0.3*Max.
`size_t` | `overlap_cost_threshold` | The number of most suitable leafs taken into account while choosing the leaf node to which currently inserted value will be added. If value is in range (0, MaxElements) - the algorithm calculates nearly minimum overlap cost, otherwise all leafs are analyzed and true minimum overlap cost is calculated. Default: 32.
