Making the DDA Run: Two-Dimensional Ray Traversal Using Runs and Runs of Runs
Iterative algorithms based on runs and runs of runs are presented to calculate the cells of the two–dimensional lattice intersected by a line of real slope and intercept. The technique is applied to the problem of traversing a ray through a two–dimensional grid. Using runs or runs of runs provides a significant improvement in the efficiency of ray traversal for all but very short path lengths w...
متن کاملtwo and three-phases fractal models application in soil saturated hydraulic conductivity estimation
introduction: soil hydraulic conductivity is considered as one of the most important hydraulic properties in water and solutionmovement in porous media. in recent years, variousmodels as pedo-transfer functions, fractal models and scaling technique are used to estimate the soil saturated hydraulic conductivity (ks). fractal models with two subset of two (solid and pore) and three phases (solid,...

متن کاملTwo phases of supersymmetric gluodynamics.
We argue that supersymmetric gluodynamics has two phases with equivalent infrared behavior, one of which is asymptotically free and another one is superstrongly coupled in the ultraviolet domain. Supersymmetric (SUSY) gauge theories are unique examples of non-trivial fourdimensional theories where some dynamical aspects are exactly tractable. The first results of this type – calculation of the ...
متن کاملWhen Short Runs Beat Long Runs
What will yield the best results: doing one run n generations long or doing m runs n/m generations long each? This paper presents a techniqueindependent analysis which answers this question, and has direct applicability to scheduling and restart theory in evolutionary computation and other stochastic methods. The paper then applies this technique to three problem domains in genetic programming....
