A Little More, a Lot Better: Improving Path Quality by a Simple Path Merging Algorithm [article]

Barak Raveh, Angela Enosh, Dan Halperin
2010 arXiv   pre-print
We introduce a simple algorithm for merging an arbitrary number of input motion paths into a hybrid output path of superior quality, for a broad and general formulation of path quality.  ...  We show that our algorithm is able to merge a handful of input paths produced by several different motion planners to produce output paths of much higher quality.  ...  This work has been supported in part by the Israel Science Foundation (grant no. 236/06), by the German-Israeli Foundation (grant no. 969/07), and the Hermann Minkowski-Minerva Center for Geometry at Tel  ...

The Ongoing Challenge – Improving Organizational Performance with Better Decisions [chapter]

Kenneth Fordyce
2010 Proceedings of the 2009 SIAM Conference on "Mathematics for Industry"  
Every organization has as a stated goal to "make smarter decisions". However, each decision is a result of a complex interaction between process (culture), data, and the models (math) used.  ...  a look back at the Ptolemaic model of the universe in terms of "selling" the model.  ...  However, the scale (Milne 2010) of the enterprise problem is too large to be solved by a single LP model. Simple heuristics such as greedy algorithms can handle the scale.  ...

A better heuristic for orthogonal graph drawings

Therese Biedl, Goos Kant
1998 Computational geometry  
Linear time and space algorithms for drawing biconnected planar graphs orthogonally with at most 2n + 4 bends on a grid of size n x n are known in the literature.  ...  The algorithm handles both planar and non-planar graphs at the same time.  ...  We provide three appendices, where we show how to compute a special planar embedding and st-ordering, how to improve the algorithm a little for simple graphs, and where we give a detailed example for a  ...

Unearthing inter-job dependencies for better cluster scheduling

Andrew Chung, Subru Krishnan, Konstantinos Karanasos, Carlo Curino, Gregory R. Ganger
2020 USENIX Symposium on Operating Systems Design and Implementation  
In simulations driven by real job logs, we find that a traditional YARN scheduler that uses Wing-provided valuations in place of user-specified priorities extracts more value (in terms of successful dependent  ...  The Wing dependency profiler analyzes job and data provenance logs to find hidden inter-job dependencies, characterizes them, and provides improved guidance to a cluster scheduler.  ...  jobs impact a lot more jobs and users than others.  ...

If in Doubt, Try Three: Developing Better Version Control Commit Behaviour with First Year Students

Amanda Berg, Simon Osnes, Richard Glassey
2022 Technical Symposium on Computer Science Education  
Results showed that students improved their commit behaviour in terms of number of commits, starting earlier with their assignments and writing more meaningful commit messages when compared to the rest  ...  Qualitative results showed that students were mostly positive towards developing better commit behaviour and felt that the extra effort to think in commits delivered proportionally more benefits for their  ...  There was a marked improvement in the quality of commit messages when comparing the test and control groups, showing that students adopted better practice.  ...

'Boxing' Choices for Better Dispute Resolution

Marc Lauritsen
2014 International Journal of Online Dispute Resolution  
This article explores opportunities for interactive visualizations in support of such processes, using as background a current software project that is developing systems for collaborative deliberation  ...  The Value-Add of Choice-Making Tools Choiceboxing can be done, in principle, with little more technology than a pencil and paper.  ...  After lots of discussion, the choice seems to hinge on three factors: completeness of features, quality of interface and ease of learning.  ...

Towards Better Response Times and Higher-Quality Queries in Interactive Knowledge Base Debugging [article]

Patrick Rodler
2017 arXiv   pre-print
The obtained picture gives a hint about which measures are more favorable in which situation or which measures always lead to the same outcomes, based on given types of queries.  ...  We tackle this issue by an in-depth mathematical analysis of diverse real-valued active learning query selection measures in order to determine qualitative criteria that make a query favorable.  ...  Therefore, minimizing D * dev by one improves RIO by more than an improvement of a query's entropy measure ENT could ever do.  ...

We study the properties of these problems and propose a range of algorithms to solve them, with different balances between complexity and quality of the result.  ...  The interpretation (i.e. decompression) of a compressed, weighted graph is that a pair of original nodes is connected by an edge if their supernodes are connected by one, and that the weight of an edge  ...  Without loss of generality, we assume that the value of any path quality function is positive, and that a larger value of q indicates better quality.  ...

2015 Algorithmic Finance  
By adapting capability from the quality control literature, we present new criteria for assessing control, expected tail loss and risk-adjusted performance in a single framework.  ...  The multi-scale capability measure we present is more descriptive and more appropriate for algorithmic trading than the traditional measure used in finance.  ...  Therefore, to accomplish this task we have developed a process that merges ideas from both finance and quality management.  ...
