Definitional Trees
Rewriting is a computational paradigm that specifies the actions, but not the control. We introduce a hierarchical structure repreat a high level of abstraction, a form of control....

Tree bitmap: hardware/software IP lookups with incremental updates
IP address lookup is challenging for high performance routers because it requires a longest matching prefix at speeds of up to 10 Gbps (OC-192). Existing solutions have poor updat...

Approximation Ratios of Multicast Light-Trees in WDM Networks
Abstract--All-optical multicast routing (AOMR) is implemented by the concept of light-tree in WDM networks. The costoptimal multicast light-tree is NP-hard to compute, especially w...

Finding Cycles and Trees in Sublinear Time
We present sublinear-time (randomized) algorithms for finding simple cycles of length at least k 3 and tree-minors in bounded-degree graphs. The complexity of these algorithms is...
