How To Install travelccm on CentOS 8
Introduction
In this tutorial we learn how to install travelccm on CentOS 8.
What is travelccm
travelccm aims at providing a clean API, and the corresponding C++ implementation, for choosing one item among a set of travel solutions, given demand-related characteristics (e.g., Willingness-To-Pay, preferred airline, preferred cabin, etc.). The travelccm C++ library implements some simple Customer Choice Models (CCM), as referenced in the literature (PhD dissertations at MIT, for instance The travelccm C++ library exposes a simple, clean and object-oriented, API. For instance, the choose() method takes, as input, both a structure representing the travel request (e.g., “from Washington, DC, US, to Beijing, China, on the 25th of May”) and a list of travel solutions (as provided by the Airline Schedule Manager project http chosen item. The output can then be used by other systems, for instance to book the corresponding travel or to visualize it on a map and calendar and to share it with others. travelccm makes an extensive use of existing open-source libraries for increased functionality, speed and accuracy. In particular the Boost (C++ Standard Extensions Install the travelccm package if you need a library of basic C++ objects for Customer-Choice Modeling (CCM), mainly for simulation purpose.
