Scientific research should be reproducible, and as such also simulation research. However, the question is - is this really the case? In some application areas of simulation, e.g., cell biology, simulation studies cannot be published without data, models, methods, including computer code being made available for evaluation. With the applications ...

Currently, only few agent-based models are implemented with a continuous representation of time, although state-of-the-art agent-based modeling and simulation (ABMS) frameworks support continuous-time models and continuous time often allows for a more faithful capturing of reality. Intrigued by this discrepancy, we take a closer look at population-based Continuous-Time Markov Chains ...

A multitude of modeling languages for simulation exists, which differ in their formal expressiveness, but also in their usability. However, to improve the practical use of a modeling language its relation to the cognitive processes of the user are often of equal interest, i.e., the learnability of a modeling language ...

In modular, hierarchical modeling, couplings (connections) describe and constrain the communication, and thus interaction, between model components. Defining couplings between a large set of components in an extensional manner—listing all existing couplings individually—often proves to be rather tedious. Moreover, if models change their structure, that is, composition and interaction patterns ...

Agent-based modeling and simulation is widely used in computational demography. Although existing agent-based approaches allow modeling linked lives in a rather flexible manner, the resulting models, due to typically being implemented in a general-purpose programming language, often lack the compactness required to easily access the model. With ML3 (Modeling Language ...

Since simulation is a tool for generating data, a major task in executing simulations is to extract data from simulation runs. However, traditional methods of data extraction such as instrumenting the model code by hand or over-instrumenting the model and filtering data offline suffer from inflexibility and poor efficiency. To ...

The state and structure of a model may vary during a simulation and, thus, also its computational demands. Adapting simulation algorithms to these demands at runtime can therefore improve their performance. While this is a general and cross-cutting concern, only few simulation systems offer reusable support for this kind of ...

Complex system-leve simulation can produce large amounts of data, of which only portions may be of interest. When experimenting with hybrid prototypes, consisting of physi-cal and simulated components, data logs are generated and inspected in real-time. Storing full data logs would not only require much disk space, it would also ...

Lattice Monte Carlo simulation of Galilei variant anomalous diffusion
April 2015
Journal of Computational Physics: Volume 288 Issue C, May 2015
Publisher: Academic Press Professional, Inc.
The observation of an increasing number of anomalous diffusion phenomena motivates the study to reveal the actual reason for such stochastic processes. When it is difficult to get analytical solutions or necessary to track the trajectory of particles, lattice Monte Carlo (LMC) simulation has been shown to be particularly useful. ...

Modeling is a creative activity known and practiced by most in industry, government, and academia. A model is a construct of language coded using different technologies---from print and physical media to computer-generated synthetic environments. The activity of modeling is so central to human cognition, that we must ask ourselves whether ...

Demographic microsimulation often focuses on effects of stable macro constraints on isolated individual life course decisions rather than on effects of inter-individual interaction or macro-micro links. To change this, modeling and simulation have to face various challenges. A modeling language is required allowing a compact, succinct, and declarative description of ...

Unambiguous experiment descriptions are increasingly required for model publication, as they contain information important for reproducing simulation results. In the context of model composition, this information can be used to generate experiments for the composed model. If the original experiment descriptions specify which model property they refer to, we can ...
