The program irace implements the iterated racing procedure, which is an extension of the Iterated F-race procedure (I/F-Race). Its main purpose is to automatically configure optimization algorithms by finding the most appropriate settings given a set of instances of an optimization problem. It builds upon the race package by Birattari and it is implemented in R. This revision documents irace ve...

The irace package implements a flexible tool for the automatic configuration of algorithms. However, irace itself has specific parameters that enable the customization of the search process according to the tuning scenario. In this paper, we analyze five parameters of irace: the number of iterations, the number of instances seen before the first elimination test, the maximum number of elite con...

Multi-Objective Evolutionary Algorithms (MOEAs) have been successfully applied to solve hard real software engineering problems. However, choose and design a MOEA is considered difficult task, since there are several parameters components be configured. These aspects directly impact the generated solutions performance of MOEAs. In this sense, paper proposes an approach for automatic generation ...

introduction: this in vitro study aimed to assess the effectiveness of a single-file rotary system (oneshape) in reduction of intracanal bacteria. methods and materials: eighty one single-rooted mandibular first premolars with single canals were used. six samples were selected as aseptic control group. seventy five remaining specimens were infected by enterococcus faecalis and incubated for 72 ...

BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...

Automatic algorithm configuration techniques have proved to be successful in finding performance-optimizing parameter settings of many search-based decision and optimization algorithms. A re-current, important step in software development is the compilation of source code written in some programming language into machine-executable code. The generation of performance-optimized machine code itse...

Abstract This paper introduces acviz , a tool that helps to analyze the automatic configuration of algorithms with irace . It provides visual representation process, allowing users extract useful information, e.g. how configurations evolve over time. When test data is available, also shows performance each on instances. Using this visualization, can and compare quality resulting observe differe...
