Preface
During th e 1991/9 2 academi c year , Fa n R . K . Chun g an d I serve d a s Co -Directors of the Specia l Year on Graph Theor y an d Algorithm s sponsore d b y th e Center fo r Discret e Mathematics an d Theoretica l Compute r Scienc e (DIMACS) . Based o n informa l feedbac k fro m som e o f th e mor e tha n 30 0 researcher s wh o traveled t o Ne w Jerse y thi s pas t yea r t o participat e i n DIMAC S activities , th e Special Yea r wa s a grea t success . Thi s admittedl y biase d vie w i s supporte d by th e growin g lis t o f accomplishment s i n whic h researcher s recogniz e th e rol e played b y DIMAC S i n initiating , fosterin g an d facilitatin g thei r work .
The Specia l Year o n Grap h Theor y an d Algorithm s feature d fou r workshops :
