ThesymposiaonFundamentalsofComputationTheoryareheldeverytwoyears. Following the tradition established at the ?rst FCT 1977, the conference brings together specialists in theoretical ?elds of Computer Science from various co- tries and stimulates mathematical research in theoretical computer science. - pics of interest for the satellite workshop onE?cientAlgorithms WEA2001 are: computational complexity, graph and network algorithms, ?ow and routing - gorithms,coloringandpartitioning,cutsandconnectivity,packingandcovering, scheduling algorithms, approximation algorithms, inapproximability results, - line problems, randomized algorithms, integer programming, semide?nite p- gramming, algorithmic geometry, polyhedral combinatorics, branch and bound algorithms, cutting plane algorithms, and various applications. The 13th FCT was held in Riga-Lielupe, August 22-24, 2001 with an - ditional day (August 25) for the satellite workshop WEA2001. The previous meetings were held in the following cities: – Poznan-K´ ornik, Poland, 1977 – Wendish-Rietz, Germany, 1979 – Szeged, Hungary, 1981 – Borgholm, Sweden, 1983 – Cottbus, Germany, 1985 – Kazan, Russia, 1987 – Szeged, Hungary, 1989 – Gosen-Berlin, Germany, 1991 – Szeged, Hungary, 1993 – Dresden, Germany, 1995 – Krak´ ow, Poland, 1997 – Iasi, Romania, 1999 Thisyearthenumberofsubmittedpaperswashigh.TheProgramCommittee decided to accept 28 submissions as regular papers and 15 submissions as short papers.
