Interview about Sarah Piatt with Dr. Paula Bernat Bennett by Dr. Elizabeth Renker
No full textInterview conducted in Arlington, Massachusetts.The media can be accessed here: http://streaming.osu.edu/knowledgebank/RareBooksManuscripts/RAR_PIATT_Renker_Bennett_interview_2017-09-10_audio.mp4Interview with Dr. Paula Bernat Bennett about how she discovered Sarah Morgan Bryan Piatt, a poet who had essentially been lost to literary history. Professor Bennett accidentally came upon Piatt in her research on women poets of the nineteenth century publishing in periodicals, and she later produced the first scholarly selected edition of Sarah’s poems since Sarah’s death in 1919: Palace-Burner: The Selected Poetry of Sarah Piatt (2001). Interview conducted in Arlington, Massachusetts, by Professor Elizabeth Renker from the Department of English at The Ohio State University

Benefits of a population: five mechanisms that advantage population-based algorithms
No full textThis paper identifies five distinct mechanisms by which a population-based algorithm might have an advantage over a solo-search algorithm in classical optimization. These mechanisms are illustrated through a number of toy problems. Simulations are presented comparing different search algorithms on these problems. The plausibility of these mechanisms occurring in classical optimization problems is discussed. The first mechanism we consider relies on putting together building blocks from different solutions. This is extended to include problems containing critical variables. The second mechanism is the result of focusing of the search caused by crossover. Also discussed in this context is strong focusing produced by averaging many solutions. The next mechanism to be examined is the ability of a population to act as a low-pass filter of the landscape, ignoring local distractions. The fourth mechanism is a population's ability to search different parts of the fitness landscape, thus hedging against bad luck in the initial position or the decisions it makes. The final mechanism is the opportunity of learning useful parameter values to balance exploration against exploitation

Genetic Drift in Genetic Algorithm Selection Schemes
No full textA method for calculating genetic drift in terms of changing population fitness variance is presented. The method allows for an easy comparison of different selection schemes and exact analytical results are derived for traditional generational selection, steady-state selection with varying generation gap, a simple model of Eshelman's CHC algorithm, and evolution strategies. The effects of changing genetic drift on the convergence of a GA are demonstrated empirically
Learning the large-scale structure of the max-sat landscape using populations
No full textA new algorithm for solving MAX-SAT problems is introduced which clusters good solutions, and restarts the search from the closest feasible solution to the centroid of each cluster. This is shown to be highly efficient for finding good solutions of large MAX-SAT problems. We argue that this success is due to the population learning the large-scale structure of the fitness landscape. Systematic studies of the landscape are presented to support this hypothesis. In addition, a number of other strategies are tested to rule out other possible explanations of the success. Preliminary results are shown indicating that extensions of the proposed algorithm can give similar improvements on other hard optimisation problems

Russell V. Morgan Papers
No full textRussell V. Morgan (1893-1952) was an American music educator, former President of the Music Educators National Conference (MENC), now known as the National Association for Music Education (NAfME), (1930-32) and MENC Hall of Fame inductee (1996). Morgan studied music education at Northwestern University where he received a BM (1915), MM (1921), and was awarded an honorary doctorate (1936). During his career, Morgan served as an army bandmaster during World War I, a church organist, a supervisor of music in public schools, and author of articles, books and school texts on music and music education. The Russell V. Morgan Papers covers the period from 1896-1998; the bulk of the materials date from 1920-1952. The collection consists of both personal and professional papers including published and unpublished writings, speeches, correspondence, programs, photographs, clippings, and articles related to the Morgans career as a music educator, his involvement with MENC, and music education and reference materials
