LION 3 the Third International Conference on Learning and Intelligent Op- mizatioN was held
during January 14-18 in Trento Italy. The LION series of conferences provides a platform for
researchers who are interested in the int- section of e?cient optimization techniques and
learning. It is aimed at exploring the boundaries and uncharted territories between machine
learning arti?cial intelligence mathematical programming and algorithms for hard optimization
problems. The considerable interest in the topics covered by LION was re?ected by the
overwhelming number of 86 submissions which almost doubled the 48 subm- sions received for
LION's second edition in December 2007. As in the ?rst two editions the submissions to LION 3
could be in three formats: (a) original novel and unpublished work for publication in the
post-conference proceedings (b) extended abstracts of work-in-progressor a position statement
and (c) recently submitted or published journal articles for oral presentations. The 86 subm-
sions received include 72 ten and four articles for categories (a) (b) and (c)
respectively.
