Precedence constrained scheduling in (2 - 7/(3p+1)) optimal
We present a polynomial time approximation algorithm for unit time precedence constrained scheduling. Our algorithm guarantees schedules which are at most 2 - 7 3p+1 factor as lon...

Retiming for DSM with Area-Delay Trade-Offs and Delay Constraints
The concept of improving the timing behavior of a circuit by relocating registers is called retiming and was first presented by Leiserson and Saxe. They showed that the problem of...

Incremental XPath evaluation
We study the problem of incrementally maintaining an XPath query on an XML database under updates. The updates we consider are node insertion, node deletion, and node relabeling. ...
