[edit] Release history

The first version of SAGE was released on 24 February 2005, with the initial goals of creating an "open source alternative to Magma, Maple, Mathematica, and MATLAB."^[1]

The lead developer of SAGE, William Stein, is a mathematician at the University of Washington who employs students for SAGE development. Most of the development of SAGE is supported by grants.^[2]

[edit] Features

SAGE combines various modes of usage for different applications.

It consists of a (local) web server for the graphical interface. This is the usual way of working with SAGE.
It provides a text-based command line interface.
It includes MoinMoin as a Wiki system for knowledge management.
It is possible to embed SAGE inside LaTeX documents.
It is possible to dynamically interact with the computations.^[3]
It provides support for distributed computing.
It offers Python interfaces for programming and integrates different open source mathematical software and libraries as the back-ends for most computations.
SAGE provides interfaces to included systems such as PARI/GP, GAP and Singular as well as interfaces to some third-party software like Mathematica, Magma, and Maple, which allows users to combine software and compare output and performance. It is thus also a "front-end" to other mathematical tools similar to GNU TeXmacs.
