This book constitutes the thoroughly refereed and extended post-proceedings of the 11th Annual ERCIM International Workshop on Constraint Solving and Constraint Logic Programming, CSCLP 2006, held in Caparica, Portugal in June 2006.

Besides papers taken from the workshop, others are submitted in response to an open call for papers after the workshop.

The 10 revised full papers presented together with a tutorial on hybrid algorithms were carefully reviewed and selected for inclusion in the book. The papers are organized in topical sections on global constraints, search and heuristics, language and implementation issues, and modeling.

From well-known Brazilian playwright Francisco Azevedo, a heartwarming debut novel about three generations of a family whose kitchen contains the secret ingredient for happiness--sure to appeal to fans of "Like Water for Chocolate."
"Once upon a time there was some rice. Rice planted in the earth, fallen from the sky, and gathered up from the stone. Rice that doesn't spoil, it came from far away, by ship with three exuberant young people filled with dreams..."
"Once Upon a Time in Rio" is a spellbinding family saga beginning with Jose Custodio and Maria Romana and their search for a prosperous future. As newlyweds, Jose and Maria immigrated to Brazil at the beginning of the twentieth century, accompanied by a special gift. During the dinner preparations to celebrate their centenary wedding anniversary, their eldest son Antonio, already a grandfather, looks back at the lives of his parents, his aunt, his brothers, their children and grandchildren, as well as his own.
Antonio knows that family is a difficult dish to get right and that happiness must be cooked up day by day; however, what separates his family from any other is its possession of a secret ingredient for happiness: the sack of magical rice given to his parents on their wedding day. With the help of the rice, whose magic is as old as fire and time, Antonio's family has been guided through the most trying of life's tribulations.
Lyrically written, "Once Upon a Time in Rio" bares the fragile yet strong nature of the human spirit and with great insight captures the solace provided by loved ones in times of need. Already an international bestseller, this is a beautifully told tale about the wisdom of past generations and the inextricable ties of family.
