The datastructures GAP package

The datastructures package aims at providing standard datastructures, consolidating existing code and improving on it, in particular in view of HPC-GAP.

The datastructures package consists of two parts: Interface declarations and implementations.

WARNING

This is a BETA release of this package. Interfaces and behaviour might change between beta releases and break your code. If you are relying on any feature and would like it to be retained, please contact us via https://github.com/gap-packages/datastructures/issues

or our slack channel #datastructures on https://gap-system.slack.com.

Interface Declarations

The goal of interface declarations is to define standard interfaces for datastructures and decouple them from the implementations. This enables easy exchangability of implementations, for example for more efficient implementations, or implementations more suited for parallelisation or sequential use.

The datastructures package declares interfaces for the following datastructures

queues
doubly linked lists
heaps
priority queues
hashtables
dictionaries

Implementations

Queues

List queues based on Reimer Behrends’ implementation in HPC-GAP
