Approximation Schemes: Transcript

for Dense Variants of Feedback Arc Set Correlation Clustering and Other Fragile Min Constraint Satisfaction Problems Warren Schudy Brown University Computer Science Joint work with. HOCHBAUM AND WOLFGANG MAASS University of California Berkeley California Abstract A unified and powerful approach is presented for devising polynomial approximation schemes for many strongly NPcomplete problems Such schemes consist of families of ap Prasad .
