th This volume contains the proceedings of the 19 FST&TCS conference (Foundations of Software Technology and Theoretical Computer Science), - ganized under the auspices of the Indian Association for Research in Computing Science (http://www. imsc. ernet. in/~iarcs). This year's conference attracted 84 submissions from as many as 25 dieren t countries. Each submission was reviewed by at least three independent referees. th After a week-long e-mail discussion, the program committee met on the 7 th and 8 of August, 1999, in Chennai and selected 30 papers for inclusion in the conference program. We thank the program committee members and the reviewers for their sincere eorts.

Moreover,theconferenceisprecededbyatwo-dayworkshop(- cember 11{12, 1999) on Data Structures and succeeded by a two-day workshop (December 16-17, 1999) on Foundations of Mobile Computation.The conference also features two joint sessions with the International Symposium on - tomata, Algorithms and Computation (December 16{18, 1999, Chennai): Monika Henzinger (Compaq Systems Research, Palo Alto, USA) is presenting a tutorial on Web algorithmics as the last event of FST&TCS and Kurt Mehlhorn (Max-Planck-Institut, Saarbru ..cken, Germany) is giving a talk on algorithm - gineering as the rst event of ISAAC.
