Gathering and utilising domain knowledge in commercial computer games
In practice, adaptive game AI in commercial computer games is seldom implemented, because machine learning techniques require numerous trials to learn effective behaviour. To allow fast adaptation in games, in this paper we describe a means of learning that is inspired by the human capability to solve problems by generalising over limited experiences with the problem domain. We compare three ap...
متن کاملNotes on Barnsley Fern
An affine transformation on the plane is a mapping T that preserves collinearity and ratios of distances: given two points A and B, if C is the middle of the segment [A,B] then T (C) is the middle of the segment [T (A), T (B)]. Translations, contractions, expansions, reflections, rotations, are all particular cases of affine transformations. In general, an affine transformation T maps a point (...
متن کاملFERNS AND FERN ALLIES OF IRAN
The pteridophyte account of Flora Iranica (ed. K.H. Rechinger) is still not published. The Caspian forests provide suitable habitats for the growth of many ferns and fern allies in Iran. In semi-arid and mountainous areas of Iran, mesophilous plants are restricted to rock crevices, waterfall proximity, stream banks and lake shores. Based on field collections and study of herbarium specimens in ...
متن کاملBetween Two Fern Genomes
Ferns are the only major lineage of vascular plants not represented by a sequenced nuclear genome. This lack of genome sequence information significantly impedes our ability to understand and reconstruct genome evolution not only in ferns, but across all land plants. Azolla and Ceratopteris are ideal and complementary candidates to be the first ferns to have their nuclear genomes sequenced. The...
متن کاملGathering thunder
It’s common to accompany the rollout of a new biomedical journal with an explanation for its coming into being, usually by suggesting there’s an unmet need, despite the panoply of existing journals. I’m not going to do that, at least not exactly. The biomedical literature is almost unimaginably vast already, much more than even the most diligent speed-reading scholar-who-listens-to-science-blog...
