On Turing complete T7 and MISC F--4 program fitnes landscapes
نویسندگان
چکیده
We use the minimal instruction set F-4 computer to define a minimal Turing complete T7 computer suitable for genetic programming (GP) and amenable to theoretical analysis. Experimental runs and mathematical analysis of the T7, show the fraction of halting programs is drops to zero as bigger programs are run.

The Halting Probability in Von Neumann Architectures
Theoretical models of Turing complete linear genetic programming (GP) programs suggest the fraction of halting programs is vanishingly small. Convergence results proved for an idealised machine, are tested on a small T7 computer with (finite) memory, conditional branches and jumps. Simulations confirm Turing complete fitness landscapes of this type hold at most a vanishingly small fraction of u...
متن کاملBayesian perspective over time
Thomas Bayes, the founder of Bayesian vision, entered the University of Edinburgh in 1719 to study logic and theology. Returning in 1722, he worked with his father in a small church. He also was a mathematician and in 1740 he made a novel discovery which he never published, but his friend Richard Price found it in his notes after his death in 1761, reedited it and published it. But until L...
متن کاملCavity Solitons in Driven VCSELs above Threshold
CSs have been theoretically predicted and recently experimentally demonstrated in broad area, vertical cavity driven semiconductor lasers (VCSELs) slightly below the lasing threshold. Above threshold, the simple adiabatic elimination of the polarization variable is not correct, leading to oscillatory instabilities with a spuriously high critical wave-number. To achieve real insight on the compl...
متن کاملSPOT PATTERNS IN GRAY SCOTT MODEL WITH APPLICATION TO EPIDEMIC CONTROL
In this work, we analyse a pair of two-dimensional coupled reaction-diusion equations known as the Gray-Scott model, in which spot patterns have been observed. We focus on stationary patterns, and begin by deriving the asymptotic scaling of the parameters and variables necessary for the analysis of these patterns. A complete bifurcation study of these solutions is presented. The main mathematic...
متن کاملTuring-complete data structure for genetic programming
In generating a program automatically, if we do not know whether the problem is solvable or not in advance, then the representation of the program must be Turing-complete, i.e. the representation must be able to express any algorithms. However, a tree structure used by the standard Genetic Programming is not Turingcomplete. We propose a representation scheme, which is a recurrent network consis...
