This paper is intended to sum up the results of the Second International Workshop on
Software Engineering for Large-Scale Multi-Agent Systems
(SELMAS'03) held in Portland, Oregon, USA, May 3--4, 2003, as part of the
International Conference on Software Engineering
(ICSE'03). The main purpose of this workshop was to share and pool the collective experience of people, both academics and practitioners, who are actively working on software engineering for large-scale multi-agent systems. The call for papers elicited some 26 submissions, of which 19 papers were accepted for presentation. A selected set of the workshop papers and invited papers are to appear in the 2
^nd^
edition of the book
Software Engineering for Large-Scale Multi-Agent Systems
(LNCS, Springer, 2003). The workshop consisted of an opening presentation, several paper presentations organized into five sessions, and three panels. During the workshop we informally reviewed ongoing and previous work and debated a number of important issues. The SELMAS'03 Web page, including the papers and the electronic version of this report, can be found at . We begin by presenting an overview of our goals and the workshop structure, and then focus on the workshop technical program.
