Partial Leader Optimizer

Stabilizing leader election in partial synchronous systems with crash failures

This article deals with stabilization and fault-tolerance. We consider two types of stabilization: the selfand the pseudostabilization. Our goal is to implement the selfand/or pseudostabilizing leader election in systems with process crashes, weak reliability, and synchrony assumptions. We try to propose, when it is possible, communication-efficient implementations. Our approach allows to obtai...

A Region Based Query Optimizer Through Cascades Query Optimizer Framework

The Cascades Query Optimizer Framework is a tool to help the database implementor DBI in constructing a query optimizer for a DBMS It is data model independent and allows to code a query optimizer by providing the implementations of the subclasses of prede ned interface classes When the implementations of the required classes are provided properly the generated optimizer produces the optimum ex...

AES 127 Optimizer

Any audio recording can be turned into a digital musical instrument by feeding it into an audio sampler. However, it is difficult to edit such a sound in musical terms or even to control it in real time with musical expression. This does not change much if a more sophisticated resynthesis method is applied. Many electronic musicians appreciate the direct and clear access to sound parameters a t...

The Hotlink Optimizer

Grey Wolf Optimizer

This work proposes a new meta-heuristic called Grey Wolf Optimizer (GWO) inspired by grey wolves (Canis lupus). The GWO algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature. Four types of grey wolves such as alpha, beta, delta, and omega are employed for simulating the leadership hierarchy. In addition, the three main steps of hunting, searching for prey, enc...
