The possibility of salvaging information from a "yes" program that is giving up, and using it to find a "no" answer is discussed. Two incomplete procedures were studied experimentally. One (based on "easy" resolutions) produces "no" answers. The other (based on Johnson's maximum satisfiability approximation algorithm) produces "yes" answers. Both are deterministic, polynomial time algorithms, quadratic with careful implementation.

It applies reasoning in the form of certain resolution operations, and identification of equivalent literals. Resolution produces growth in the size of the formula, but within a global quadratic bound; most previous methods avoid operations that produce any growth, and generally do not identify equivalent literals. Computational experience so far suggests that the method does substantially less "guessing" than previously reported algorithms, while keeping a polynomial time bound on the work done between guesses. However, the time trade-off between reasoning and guessing is not yet clear. }", ANNOTE2="{ We present experimental data comparing six branching strategies of the proposed algorithm on a variety of problems, including several Dimacs benchmarks. These branching strategies were shown to be different with statistical significance and a new scheme based on Johnson's maximum satisfiability approximation algorithm was the best on random 3-CNF formulas. In addition to the choice of a branching strategy, we found that {\it variable reordering} can significantly impact the performance for many classes of problems in the Dimacs benchmark. We have also tested both satisfiable and unsatisfiable random 3-CNF formulas with 50-283 variables and 4.27 ratio of clauses to variables; this class is generally acknowledged to be relatively "hard" and required extensive backtracking by other algorithms. The new algorithm has solved them with surprisingly little backtracking: for 200 variables at this ratio, the average number of guesses was 2,955 and the average CPU time was 119 seconds on SunSS10/41. }", ANNOTE3="{ For 283 variables, the average number of guesses was 57,503 with the values ranging from 105 to 182,006 in a set of 100 random formulas. We have also observed that unsatisfiable random problems do not follow the easy-hard-easy pattern. Our results indicate an exponential growth rate of $2^{.004L}$ for random formulas, where $L$ is the number of \emph{occurrences} of literals in the formula. Larger unsatisfiable formulas from circuit-fault analysis, with 500--10400 variables were solved with \emph{no} backtracking in some cases. }" } % ==> leaner05.bib <== @ARTICLE{VanGelder05-leaner, author = "Van Gelder, Allen", Title = "Toward Leaner Binary-Clause Reasoning in a Satisfiability Solver", journal = "Annals of Mathematics and Artificial Intelligence", volume = "43", number = "1--4", pages = "239--253", NOTE = "(Preliminary version appeared in SAT02, Cincinnati)", year = 2005 } % ==> lemmas-dist.bib <== @ARTICLE{VanGelderOkushi99-AMAI-Lemmas, author = "Van Gelder, Allen and Fumiaki Okushi", title = "Lemma and Cut Strategies for Propositional Model Elimination", journal = "Annals of Mathematics and Artificial Intelligence", volume = "26", number = "1--4", pages = "113--132", year = 1999 } % ==> lics01-sat.bib <== @INPROCEEDINGS{VG01-lics-sat, Author = "Van Gelder, Allen", Title = "Combining Preorder and Postorder Resolution in a Satisfiability Solver", BOOKTITLE = "IEEE/ASL LICS Satisfiability Workshop", PUBLISHER = "", ADDRESS = "Boston", PAGES = "", YEAR = "2001" } % ==> mdh94.bib <== @INPROCEEDINGS{Wilhelms94b, AUTHOR = "Jane Wilhelms and Van Gelder, Allen", TITLE = "Multi-Dimensional Trees for Controlled Volume Rendering and Compression", BOOKTITLE = "ACM Symposium on Volume Visualization 1994", MONTH = "October", ADDRESS = "Washington, D.C.", NOTE = "See also technical report UCSC-CRL-94-02", PAGES = "27--34", YEAR = "1994" } % ==> mirrors94.bib <== @INPROCEEDINGS{VanGelder94, AUTHOR = "Van Gelder, Allen and Jane Wilhelms", TITLE = "Doing It with Mirrors: Low Budget Stereo Graphics", BOOKTITLE = "IS\&T\/SPIE Electronic Imaging: Science and Technology", YEAR = "1994", MONTH = "February 7--8", PAGES = "68--77", NOTE = "Also University of California technical report UCSC-CRL-93-22", ANNOTE = "UCSC CIS Department, Applied Sciences Building, Santa Cruz, CA 95064" } % ==> modoc-ub-dist.bib <== @ARTICLE{ VG97-modoc-ub-DAM, AUTHOR = "Van Gelder, Allen", TITLE = "Complexity Analysis of Propositional Resolution with Autarky Pruning", JOURNAL = "Discrete Applied Mathematics", VOLUME = "96--97", PAGES = "195--221", YEAR = 1999 } % ==> nail86.bib <== @INPROCEEDINGS( MUV86, AUTHOR = "Morris, K. and Ullman, J.

In particular, they are often used to track critical points in time-dependent vector fields and to extract and track vortex core lines. The general idea is to extract the feature or its temporal evolution using a stream line integration in a derived vector field - the so-called Feature Flow Field (FFF). Hence, the desired feature line is a stream line of the FFF. As we will carefully analyze in this paper, the stream lines around this feature line may diverge from it. This creates an unstable situation: if the integration moves slightly off the feature line due to numerical errors, then it will be captured by the diverging neighborhood and carried away from the real feature line. The goal of this paper is to define a new FFF with the guarantee that the neighborhood of a feature line has always converging behavior. This way, we have an automatic correction of numerical errors: if the integration moves slightly off the feature line, it automatically moves back to it during the ongoing integration. This yields results which are an order of magnitude more accurate than the results from previous schemes. We present new stable FFF formulations for the main applications of tracking critical points and solving the Parallel Vectors operator. We apply our method to a number of data sets.
