Reduce (computer algebra system)

REDUCE is a general-purpose <a href="/facts/Computer_algebra_system/jkLAC1U3">computer algebra system</a> originally geared towards applications in physics.
The development of REDUCE was started in 1963 by <a href="/facts/Anthony_C._Hearn/LnR7q9vH">Anthony C. Hearn</a>; since then, many scientists from all over the world have contributed to its development. REDUCE was <a href="/facts/Open-source_software/HzTaB8E9">open-sourced</a> in December 2008 and is available for free under a <a href="/facts/Modified_BSD_license/XLtmLp5x">modified BSD license</a> on <a href="/facts/SourceForge/lxYAgUAX">SourceForge</a>. Previously it had cost $695.
REDUCE is written entirely in its own <a href="/facts/Lisp_/xJHA3CrX">Lisp</a> dialect called Standard Lisp, expressed in an <a href="/facts/ALGOL/wlFJGNEx">ALGOL</a>-like syntax called RLISP that is also used as the basis for REDUCE's user-level language.
Implementations of REDUCE are available on most variants of <a href="/facts/Unix/0pNL2seI">Unix</a>, <a href="/facts/Linux/9FvCKSTq">Linux</a>, <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a>, or <a href="/facts/Apple_Macintosh/8GhnXTK0">Apple Macintosh</a> systems by using an underlying <a href="/facts/Portable_Standard_Lisp/15IY7nf5">Portable Standard Lisp (PSL)</a> or Codemist Standard Lisp (CSL) implementation. CSL REDUCE offers a <a href="/facts/Graphical_user_interface/wBlQFWDP">graphical user interface</a>. REDUCE can also be built on other Lisps, such as <a href="/facts/Common_Lisp/mq1pRbSF">Common Lisp</a>.
