TWEAKing death

The perils of tweaking: how to use macrodata to set parameters in complex simulation models

When can macroscopic data about a system be used to set parameters in a microfoundational simulation? We examine the epistemic viability of tweaking parameter values to generate a better fit between the outcome of a simulation and the available observational data. We restrict our focus to microfoundational simulations—those simulations that attempt to replicate the macrobehavior of a target sys...

Process-based Software Tweaking with Mobile Agents

We describe an approach based upon software process technology to on-the-fly monitoring, redeployment, reconfiguration, and in general adaptation of distributed software applications, in short “software tweaking”. We choose the term tweaking to refer to modifications in structure and behavior that can be made to individual components, as well as sets thereof, or the overall target system config...

Population Dynamics of Centipede Game using an Energy Based Evolutionary Algorithm

In the context of Evolutionary Game Theory, we have developed an evolutionary algorithm without an explicit fitness function or selection function. Instead players obtain energy by playing games. Clonal reproduction subject to mutation occurs when a player’s energy exceeds some threshold. To avoid exponential growth of the population there is a death event that depends on population size. By tw...

Untidy Mind

The sonification of data in this piece is not consciously shaped by any guiding metaphor, but has developed through tinkering with and tweaking various synthesis methods while listening for coherences and differences in the sound field.
