Non-Schedulability Conditions for Off-line Scheduling of Real-Time Systems Subject to Precedence and Strict Periodicity Constrai
Classical off-line approaches based on preemption such as RM (Rate Monotonic), DM (Deadline Monotonic), EDF (Earliest Deadline First), LLF (Least Laxity First), etc, give schedula...

Improved Approximations for TSP with Simple Precedence Constraints
In this paper, we consider variants of the traveling salesman problem with precedence constraints. We characterize hard input instances for Christofides' algorithm and Hoogeve...

On the complexity of the Eulerian closed walk with precedence path constraints problem
The Eulerian closed walk problem in a digraph is a well-known polynomial-time solvable problem. In this paper, we show that if we impose the feasible solutions to fulfill some pre...

System-on-a-chip test scheduling with precedence relationships, preemption, and power constraints
Test scheduling is an important problem in system-on-a-chip (SOC) test automation. Efficient test schedules minimize the overall system test application time, avoid test resource c...

Topological Dependency Trees: A Constraint-Based Account of Linear Precedence
We describe a new framework for dependency grammar, with a modular decomposition of immediate dependency and linear precedence. Our approach distinguishes two orthogonal yet mutua...
