The Decentralized Pianola: Evolving Mechanical Music Instruments Using a Genetic Algorithm

چکیده

This paper presents computer experiments concerning the decentralized pianola, a hypothetical mechanical music instrument, whose large-scale musical behavior is the result of local physical interactions between simple elements. Traditional mechanical music instruments like the pianola and the music box rely for their operation on the separation between a sequential memory unit and an execution unit. In a decentralized mechanical instrument, musical memory is an emergent global property of the system, undistinguishable from the execution process. Such a machine is both a score and an instrument. The paper starts by discussing the difference between sequential memory systems and systems exhibiting emergent decentralized musical behavior. Next, the use of particle system simulation for exploring virtual decentralized instruments is demonstrated, and the architecture for a simple decentralized instrument is outlined. The paper continues by describing the use of a genetic algorithm for evolving decentralized instruments that reproduce a given musical behavior.

A MULTI-OBJECTIVE DECENTRALIZED MULTIPLE CONSTRUCTION PROJECTS SCHEDULING PROBLEM CONSIDERING PERIODIC SERVICES AND ORDERING POLICIES

In decentralized construction projects, costs are mostly related to investment, material, holding, logistics, and other minor costs for implementation. For this reason, simultaneous planning of these items and appropriate scheduling of activities can significantly reduce the total costs of the project undertaken. This paper investigates the decentralized multiple construction projects schedulin...

An optimization technique for vendor selection with quantity discounts using Genetic Algorithm

Vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. The problem of vendor selection becomes still more compli-cated with the inclusion of incremental discount pricing schedule. Such hard combinatorial problems when solved using meta heuristics produce near optimal solutions. This paper propose...
