Grammatical Evolution: A Steady State approach
We describe a Genetic Algorithm that can evolve complete programs. Using a variable length linear genome to govern the mapping of a Backus Naur Form grammar definition to a program, expressions and programs of arbitrary complexity may be evolved. Our system, Grammatical Evolution, has been applied to problems such as a Symbolic Regression problem, and finding Trigonometric Identities. In this p...
متن کاملAN EQUATION ORIENTED APPROACH TO STEADY STATE FLOWSHEETING OF METHANOL SYNTHESIS LOOP
An equation-oriented approach was developed for steady state flowsheeting of a commercial methanol plant. The loop consists of fixed bed reactor, flash separator, preheater, coolers, and compressor. For steady sate flowsheeting of the plant mathematical model of reactor and other units are needed. Reactor used in loop is a Lurgi type and its configuration is rather complex. Previously reactor ...
متن کاملStress evolution to steady state in ion bombardment of silicon
Low temperature ion bombardment of initially crystalline, defect-free silicon with 700 eV ion beam energy creates a highly-damaged stressed layer a few nanometers thick on the surface. An apparent steady state in structure is achieved at a fluence of 2 · 10–3 · 10 ions/cm. In this work, the stresses are computed using the interatomic force definition of stress. The stress evolution is studied a...
متن کاملApproach to the nonequilibrium time-periodic state in a steady shear flow model
The standard nonequilibrium molecular dynamics algorithm for steady shear flow (SLLOD ) employs Lees–Edwards periodic boundary conditions. It is not widely known that these boundary conditions make the system non–autonomous. The "steady state" shear stress is in fact time periodic. The standard response theory derivations for steady shear do not take proper account of these non–autonomous terms...
متن کاملA Discrete-Time Approach to the Steady-State and Stability Analysis of Distributed Nonlinear Autonomous Circuits
We present a direct method for the steady-state and stability analysis of autonomous circuits with transmission lines and generic nonlinear elements. With the discretization of the equations that describe the circuit in the time domain, we obtain a nonlinear algebraic formulation where the unknowns to determine are the samples of the variables directly in the steady state, along with the oscill...
