This event was organized by the Department of Computer Science and Engineering, Indian Institute of Technology Madras. Theworkshopcoveredadiverserangeoftopicsonalgorithmsandcomputations includingcomputationalgeometry,approximationalgorithms,graphalgorithms, parallelanddistributedcomputing,graphdrawing,andcomputationalcomplex- ity. This volume contains 29 contributed papers presented during WALCOM 2014. There were 62 submissions from 16 countries. These submissions were rigorouslyrefereedby the ProgramCommittee members with the help of exter- nal reviewers. Abstracts of three invited talks delivered at WALCOM 2014 are also included in this volume. We would like to thank the authors for contributing high-quality research papers to the workshop. We express our heartfelt thanks to the ProgramCom- mittee members and the external referees for their active participation in re- viewing the papers. We are grateful to Kurt Mehlhorn, Ian Munro, and Pavel Valtrfordeliveringexcellentinvitedtalks.WethanktheOrganizingCommittee, chairedbyN.S.Narayanaswamyforthesmoothfunctioningoftheworkshop.We thank Springer for publishing the proceedings in the reputed Lecture Notes in Computer Science series. We thank our sponsors for their support. Finally, we remarkthatthe EasyChairconferencemanagementsystemwasveryeffective in handling the reviewing process.
