Traveling Salesman Problem: A Foveating Pyramid Model, Zygmunt Pizlo, Emil Stefanov, John Saalweachter, Zheng Li, Yll Haxhimusa, Walter G. Kropatsch

The Journal of Problem Solving

We tested human performance on the Euclidean Traveling Salesman Problem using problems with 6–50 cities. Results confirmed our earlier findings that: (a) the time of solving a problem is proportional to the number of cities, and (b) the solution error grows very slowly with the number of cities. We formulated a new version of a pyramid model. The new model has an adaptive spatial structure, and it simulates visual acuity and visual attention. Specifically, the model solves the E-TSP problem sequentially by moving attention from city to city, the same way human subjects do. The model includes a parameter representing …

Optimizing And “Pessimizing”: Human Performance With Instructional Variants Of The Traveling Salesperson Problem, Edward Chronicle, James Macgregor, Thomas Ormerod

The Journal of Problem Solving

The two-dimensional Traveling Salesperson Problem (TSP) requires finding the shortest tour through n locations. Untrained adults are adept at the task, and reliably outperform simple construction algorithms for n up to 60. Performance may stem from a specific, inherent ability. Alternatively, it may reflect general spatial intelligence, whether inherent or acquired. If the latter holds, then people should be equally adept at finding longest tours. Two experiments comparing ability in the two tasks found participants significantly better at finding short than long tours. Furthermore, human performance was significantly worse than a simple construction algorithm (furthest-neighbor) for the task of finding …

Perceptual Or Analytical Processing? Evidence From Children's And Adult's Performance On The Euclidean Traveling Salesperson Problem, Iris Van Rooij, Alissa Schactman, Helena Kadlec, Ulrike Stege

The Journal of Problem Solving

The Euclidean Traveling Salesperson Problem (E-TSP) is a useful task to study how humans optimize when faced with computational intractability. It has been found that humans are capable of finding high-quality solutions for E TSP in a relatively short time and with seemingly little cognitive effort. This observation has led to two general proposals: The high quality of performance on E-TSP reflects (a) the output of automatic and innate perceptual processes or (b) a fundamentally intelligent approach to the task by humans. An experiment was performed to compare performance of three age groups (7- year-olds, 12-year-olds, and adults). Our findings …

A Comparison Of Heuristic And Human Performance On Open Versions Of The Traveling Salesperson Problem, James N. Macgregor, Edward P. Chronicle, Thomas C. Ormerod

The Journal of Problem Solving

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally intractable and, as with the standard TSP, people appear to be able to find good solutions with relative ease. The three heuristics used mechanisms that have been cited as potentially relevant in human performance in the standard task. These were: convex hull, nearest neighbor, and …

Human Performance On Visually Presented Traveling Salesperson Problems With Varying Numbers Of Nodes, Matthew Dry, Michael D. Lee, Douglas Vickers, Peter Hughes

The Journal of Problem Solving

We investigated the properties of the distribution of human solution times for Traveling Salesperson Problems (TSPs) with increasing numbers of nodes. New experimental data are presented that measure solution times for carefully chosen representative problems with 10, 20, . . . 120 nodes. We compared the solution times predicted by the convex hull procedure proposed by MacGregor and Ormerod (1996), the hierarchical approach of Graham, Joshi, and Pizlo (2000), and by five algorithms drawn from the artificial intelligence and operations research literature. The most likely polynomial model for describing the relationship between mean solution time and the size of a …

Are Individual Differences In Performance On Perceptual And Cognitive Optimization Problems Determined By General Intelligence?, Nicholas R. Burns, Michael D. Lee, Douglas Vickers

The Journal of Problem Solving

Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in solving the problem, and the need to optimize the solution subject to multiple interacting constraints. There are reliable individual differences in people’s abilities to solve such realistic problems. It also seems likely that people’s ability to solve these difficult problems reflects, or depends on, their intelligence. We …

Visual Learning Objects: Enable Faculty To Focus On Active Learning, Pandeli Glavanis Dr.

Faculty Journal Articles

In two recent issues of New Chalk Talk (Vol.6, Issue 2 & 6) I suggested that “learning objects” enhance active learning and that “visual learning objects”, in particular, contribute significantly to the learning relationship. In this issue I wish to elaborate on how such “visual learning objects” are the key element that liberates faculty from having to design and construct their own demonstrations and illustrations (reinvent the wheel) in their respective courses and thus enable them to focus on critical and active learning instead.

Use Of Hidden Markov Models For Qtl Mapping, Karl W. Broman

Johns Hopkins University, Dept. of Biostatistics Working Papers

An important aspect of the QTL mapping problem is the treatment of missing genotype data. If complete genotype data were available, QTL mapping would reduce to the problem of model selection in linear regression. However, in the consideration of loci in the intervals between the available genetic markers, genotype data is inherently missing. Even at the typed genetic markers, genotype data is seldom complete, as a result of failures in the genotyping assays or for the sake of economy (for example, in the case of selective genotyping, where only individuals with extreme phenotypes are genotyped). We discuss the use of …

Give Me Equity Or Give Me Death - The Role Of Competition And Compensation In Building Silicon Valley, Richard A. Booth

Faculty Scholarship

In this essay, I argue that the preeminence of Silicon Valley as an incubator of technology companies is attributable to equity compensation. Ronald Gilson, relying on the work of AnnaLee Saxenian and others who have noted the tendency of Silicon Valley employees to job hop, has suggested that California law prohibiting the enforcement of non-compete agreements was a major factor in the rise of Silicon Valley (and the demise of Route 128). I extend this line of thought by suggesting that California employers may have relied on equity compensation as a substitute way to bind employees. I argue further that …

Multi-Variant Analysis Of Real-World Environmental Variables Affecting Image Fading On Outdoor Synthetic Inkjet Substrates, Elizabeth Kline

Theses

The permanence of large format, outdoor inkjet signs is a concern for many advertisers and companies creating signs that will be displayed for years or months in such an environment. The permanence industry has focused their research on using equipment to simulate these outdoor conditions the prints face to gauge their fading properties. This research took a more direct approach by placing the prints in an actual outdoor environment and tracking the rate of color change (∆Eab), and the environmental variables. A multiple regression analysis of the data was then used to create prediction models and to eliminate environmental variables …

Effects Of Visual Distractions In The Classroom Environment On The Time On Task Of Elementary Students With Adhd, Kate E. S. Harris

Theses & Honors Papers

The focus of this study is to demonstrate that the visual distractions, narrowly defined as wall decoration, in an elementary classroom can be a factor in the amount of time students with ADHD spend on-task in that classroom. This study builds upon the information revealed by studies conducted by such researchers as Creekmore (1987), Cruickshank (1967), Doyle, Anderson, and Halcomb (1976), and Steinkamp (1980), which tested the effects of visual distractions on participants with ADD/HD . These studies did not use learning tasks and used distractions that are not typical to an elementary classroom. This study attempted to answer the …

Synthesis Of Branched Carbon Nanotubes, Apparao M. Rao, Nicholas W. Gothard, Jay B. Gaillard

Clemson Patents

The present invention discloses a relatively simple CVD method for forming branched carbon nanotubes. In general, the method includes adding a dopant to the precursor materials. The dopant can be a material that has a thermodynamically more favorable carbide-forming reaction at the reactor conditions than does the catalyst that is provided to the reactor by a second precursor material. The doped nanoparticles formed in the reactor can adhere to the walls of the developing nanotubes and provide a nucleation site for the development of one or more branches on the nanotube. The nanotubes formed according to the invention can be …
