abstract = { In classical CLP(FD) systems, domains of variables are completely
known at the beginning of the constraint propagation process.
However, in systems interacting with an external environment, this
assumption may lead to waste of computation time, or even to
obsolescence of the acquired data at the time of use.
For such cases, the Interactive Constraint Satisfaction Problem
(ICSP) model has been proposed as an extension of the CSP model, to
make it possible to start constraint propagation even when domains are
not fully known, performing acquisition of domain elements only when
necessary and without the need to restart propagation after every
acquisition.
In this paper, we present a two sorted CLP language to express and
solve ICSPs, and its implementation in the Constraint Handling Rules
(CHR) language, a declarative language particularly suitable for
high level implementation of constraint solvers.},

understanding of abductive reasoning in logic programming, and
extends it in several directions. The new features include the
ability to reason with a dynamic knowledge base, where new facts
can be added anytime, the ability to generate expectations about
such new facts occurring in the future (forecasting), and the
process of confirmation/disconfirmation of such expectations.},

two years of the SOCS project, with respect to the task of
modelling interaction amongst CL-based agents. It describes the
SOCS social model: an agent interaction specification and
verification framework equipped with a declarative and
operational semantics, expressed in terms of abduction. The
operational counterpart of the proposed framework has been
implemented and integrated in SOCS-SI, a tool that can be used
for on-the-fly verification of agent compliance with respect to
specified protocols.},

title = {Expressing Interaction in Combinatorial Auction through Social Integrity Constraints},
journal = {Intelligenza Artificiale},
year = {2005},
pages = {22--29},
volume = {{II}},
number = {1},
abstract = {Combinatorial Auctions are an attractive
application of intelligent agents; their applications are
countless and are shown to provide good revenues. On the other
hand, one of the issues they raise is the computational complexity
of the solving process (the Winner Determination Problem, WDP),
that delayed their practical use. Recently, efficient solvers have
been applied to the WDP, so the framework starts to be viable.
%
A second issue, common to many other agent systems, is {\em
trust}: in order for an agent system to be used, the users must
{\em trust} both their representative and the other agents
inhabiting the society: malicious agents must be found, and their
violations discovered. The SOCS project addresses such issues, and
provided a language, the social integrity constraints, for
defining the allowed interaction moves, together with a proof
procedure able to detect violations.
%
In this paper we show how to write a protocol for the
combinatorial auctions by using social integrity constraints. In
the devised protocol, the auctioneer interacts with an external
solver for the winner determination problem.},
