LimitedInfection
Requires Java 1.8 Maven 3.x
LimitedInfection serves as the manager for the initial infection and spread of an "infection", or feature. It allows for deployment of new feature while maintaining consistency between coaches and students.
If A coaches B and we give A a new feature, B should also get the feature. If B also coaches C then C should also get the feature. Because the infection is transferred by both the "coaches" and "is coached by" relationship, if instead we want to give C the feature, both B and A should still also get the feature. The infection controller offers two different approaches to infection.
Assumptions: For the limitedInfection case, I prioritized maintaining consistency within a classroom. All coaches and students MUST have the same feature, or none of them should have the new feature if there is no path satisfying the limit condition.
I didn't combine multiple disjointed paths to get the best infection (closest to the given limit). My limitedInfection implementation finds the one connected path with size closest to the given limit.
To improve in the future, I could implement a subset-sum algorithm to find the best combination of starting points to find the true closest infection(s) to the limit.
How to build/run project: Go to directory limitedInfection and run mvn clean install
How to run visualization: java -jar target/limitedInfection-0.0.1-SNAPSHOT-jar-with-dependencies.jar [type_of_visualize(limited: 0, total : 1), size_of_graph, limit or start_node_index]
Limited Infection Visualize: [type_of_visualize = 0, size_of_graph, limit] Total Infection Visualize: [type_of_visualize = 1, size_of_graph, start_node_index]
e.g. java -jar target/limitedInfection-0.0.1-SNAPSHOT-jar-with-dependencies.jar 0 50 20 This will visualize a limited infection on a graph of 50 users and a limit of 20 users. e.g. java -jar target/limitedInfection-0.0.1-SNAPSHOT-jar-with-dependencies.jar 1 50 6 This will visualize a total infection on a graph of 50 users starting from user/node #6.
Red represents infected, while black represents not infected.
