Better approximations for max TSP
We combine two known polynomial time approximation algorithms for the maximum traveling salesman problem to obtain a randomized algorithm which outputs a solution with expected va...

Generalizing parametric timing analysis
In the design of real-time and embedded systems, it is important to establish a bound on the worst-case execution time (WCET) of programs to assure via schedulability analysis tha...

Instruction Scheduling with Release Times and Deadlines on ILP Processors
ILP (Instruction Level Parallelism) processors are being increasingly used in embedded systems. In embedded systems, instructions may be subject to timing constraints. An optimisi...
