An Analysis of Parameters of irace
نویسندگان
چکیده
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 configurations, the statistical test and the confidence level of the statistical test. These parameters define some key aspects of the way irace searches and identifies good configurations. Originally, their values have been set based on rules of thumb and an intuitive understanding of the configuration process. This work aims at giving insights about the sensitivity of irace to these parameters in order to provide guidance for their settings and possible further improvements of irace.

The irace Package: Iterated Racing for Automatic Algorithm Configuration
The irace package implements the iterated racing procedure, which is an extension of Iterated F-race (I/F-Race). The main use of irace is the automatic configuration of optimization algorithms, that is, finding the most appropriate settings of an optimization algorithm given a set of instances of an optimization problem. It builds upon the race package by Birattari and it is implemented in R. T...

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...

متن کاملAutomatic Design of a Hybrid Iterated Local Search for the Multi-Mode Resource-Constrained Multi-Project Scheduling Problem
This paper details our submission to the MISTA 2013 challenge, which deals with the multi-mode resource-constrained multi-project scheduling problem (MRCMPSP). Kolisch and Hartmann [4] recommend metaheuristics as the best-performing methods when tackling the resource-constrained project scheduling problem with a single project and without multiple-modes. Most of these metaheuristics share many ...
