Introduction
Published in Francisco Martín Rico, A Concise Introduction to Robot Programming with ROS2, 2023
Packages can be installed from sources or with the system installation system. On Ubuntu Linux 20.04, which is the reference in this book, it is carried out with deb packages using tools like apt. Each ROS2 package is packaged in a deb package. The names of deb packages in a distribution are easily identifiable because their names start with ros- < distro > - < ros2 package name >. In order to access these packages, configure the APT ROS2 repository:

The use of expert assessment methods and cluster analysis in various industries is the focus of the work of Russian scientists (Beshelev & Gurvich. 1980), (Frenkel. 1977), (Vartazarov, Gorlov, Minaev, & Khvastunov. 1981) and foreign scientists (Bann & Farmer. 1987), (Draper & Smith. 1973), (Duran & Odell. 1977), (Kendall. 1975), (Lee & Deb. 2018), (Liao & He. 2018), (Ioppolo, Boffardi & Ar-bolino. 2019), (Meschede, Esparcia, Holzapfel & Bertheau. 2019).

Combining mutual information and stable matching strategy for dynamic evolutionary multi-objective optimization
Published in Engineering Optimization, 2018
In this section, first experiments are carried out to compare MOEA/MISTM with some DMOEAs on the FDA test suite and the UDF test suite. The compared algorithms include MOEA/DEMO (Farina et al., 2004), PPS (Zhou et al., 2007), DNSGA-II (Deb and Karthik 2007), DQMOO/AR (Hatzakis and Wallace 2006), MOEA/D-BR (Zhang and Li 2007) and MOEA/CER (Biswas et al., 2014). Results are shown in Table 4. From Table 4, it is observed that MOEA/MISTM obtains the best MIGD value in 6 out of 12 test instances. Specifically, MOEA/MISTM performs the best on FDA1, FDA3, UDF3, UDF6, UDF7 and UDF8. For the other problems, MOEA/CER, MOEA/D-BR and DQMOO/AR have their own strong points. MOEA/CER outperforms the other algorithms on UDF1, UDF5 and UDF9. MOEA/D-BR obtains the best metric values while MOEA/MISTM ranks second. DQMOO/AR shows the best performance on UDF4 instance. MOEA/MISTM performs the worst on UDF1 and UDF5.

To investigate how MitS could work under ideal conditions without technical challenges like ‘resolution, FOV, position tracking, and outdoor contrast’ (Kapler et al. 2019, 1), a virtual environment simulation was developed for testing. VR has previously been shown to be an effective substitute for AR displays in experimentation (Deb et al. 2017; Durgin and Li 2010).
