The papers during this quantity have been offered on the 6th Workshop on Algorithms and knowledge buildings (WADS '99). The workshop happened August eleven - 14, 1999, in Vancouver, Canada. The workshop alternates with the Scandinavian Workshop on Algorithms thought (SWAT), carrying on with the culture of SWAT and WADS beginning with SWAT'88 and WADS'89. according to this system committee's demand papers, seventy one papers have been submitted. From those submissions, this system committee chosen 32 papers for presentation on the workshop. as well as those submitted papers, this system committee invited the subsequent researchers to offer plenary lectures on the workshop: C. Leiserson, N. Magnenat-Thalmann, M. Snir, U. Vazarani, and 1. Vitter. On behalf of this system committee, we want to specific our appreciation to the six plenary academics who approved our invitation to talk, to the entire authors who submitted papers to W ADS'99, and to the Pacific Institute for Mathematical Sciences for his or her sponsorship. ultimately, we want to specific our gratitude to all of the those that reviewed papers on the request of this system committee.

The final part century has visible the improvement of many organic or actual theories that experience explicitly or implicitly concerned medial descriptions of items and different spatial entities in our international. at the same time, mathematicians have studied the homes of those skeletal descriptions of form, and, motivated through the various parts the place medial versions are necessary, desktop scientists and engineers have constructed a number of algorithms for computing and utilizing those versions.

Example text

For each perfect matching M in G' there exists a solution A in G with 1-1 correspondence between replacements in M and edges in A where each edge e E A corresponds to one of its own replacements. Conversely, for every solution A in G there exist a perfect matching M in G' with such correspondence. We will assure the strong equivalence using the following lemma. Lemma 3 Properties (1), (2) and (3) are sufficient to assure strong equivalence between G and G 1 : (1) For any edge {u, v}, there is a node which is incident to all replacements of {u, v}.

From this definition follows that P and Q have monotone parameterizations 0' and (3 such that O'(t) is in the neighborhood of (3(t). 1. N(q) is a continuous subset of PjPj+1 or (Pj,Pj+I,Pj+2), resp. 2. Let Q have Frechet distance at most ( to P. Let 0' and (3 be monotone parameterizations of P and Q,such that 1100(t) - {3(t)112 ::; ( for all t E [0,1]. If (3(t) = q then O'(t) E N(q), t E [0,1]. Property 7. A C-oriented line approximation Q of P has Frechet distance at most ( to P if and only if the neighborhood of Q contains P and for any two points q' and q" on Q where q' precedes q" on Q the neighborhood of q" does not precede the neighborhood of q" on P: = = (PI, ...

Vidhani }(Dcs . ucla. edu Abstract. Given a graph G with weighted edges, and a subset of nodes T, the T-join problem asks for a minimum weight edge set A such that a node u is incident to an odd number of edges of A iff u E T. We describe the applications of the T-join problem in sparse graphs to the phase assignment problem in VLSI mask layout and to conformal refinement of finite element meshes. We suggest a practical algorithm for the Tjoin problem. In sparse graphs, this algorithm is faster than previously known methods.
