Cumulus,
a chess program by Jean-Christophe Weill, in association with Marc-François Baudot. Cumulus played the WMCCC 1990, WMCCC 1991, and WCCC 1992 [1], the Aegon 1993 and various Aubervilliers Rapid Open.
Cumulonimbus and Cumulus clouds [2]

Description

from Don Beal's WMCCC 1991 report [3] :
Written by Jean-Christophe Weill, in association with Marc-François Baudot of Échec, this is a new program, only in development for 7 months, although it made its first appearance at the 1990 World Micro. Its evaluation function has some overlap with Échec, although Cumulus add hung-piece considerations, king safety and uses different definition of mobility. Its selectivity is driven by swap-off values and certain mate threats. Checks, promotions threats, and re-captures are extended.
