It has been observed that in many of the benchmark planning domains, atomic goals can be reached with a simple polynomial exploration procedure, called IW, runs time exponential problem width. Such problems have indeed bounded width: width does not grow number variables and is often no greater than two. Yet, while notion become part state- of-the-art algorithms like BFWS, there still good expla...

To each link $L$ in $S^{3}$ we associate a collection of certain labelled directed trees, called width trees. We interpret some classical and new topological invariants terms these trees show how the geometric structure can bound values from below. also that tree is associated with knot if it meets high enough “distance threshold” is, up to equivalence, unique realizing invariants.

anthropometry, a useful method for evaluating craniofacial soft tissues, makes the quantitative description of the face possible. it also assesses the degree of disharmony and imbalance in the growth and development of the face. the aim of this study was to examine the overall common age-related changes of nasomaxillary complex of adolescent boys in northeast iran. three- hundred- twelve 12 to ...
