EPOS

Installation and setup

1. Download the EPOS source code from the latest release 0.0.4.

2. Make sure that a version of Oracle Java 8 is installed. You can download it from here.

3. Downloaded files should include: datasets/, conf/, and src/.

Run I-EPOS

1. Choose dataset in datasets/. Default is gaussian with 10 agents' plans file and the goal-signal target. Each plan has the same size, consisting of plan cost (before ":") and plan values (after ":"). The goal-signal has the same dimensions as the plan dimensions. You can download other dataset from here.

2. Config parameters in conf/epos.properties based on the dataset you choose, including the number of agents, plans, iterations, simulations, children and the plan dimension. Fixed configs constain conf/log4j.properties, conf/measurement.conf, and conf/protopeer.conf.

3. Run from command line. Navigate to the project directory and execute:

cd EPOS
mvn clean install –U #or where the project pom.xml is

Or, navigate the Release-0.0.4.zip, and run from command line:

java -jar IEPOS-Tutorial.jar

Once it successfully finishes, the project can be opened via your IDE of choice as a Maven project.

Results output

After running, results are shown in output/ directory. The output constains:

• Log output from the loggers in ".csv" format.
• A copy of the applied configuration for sanity checks named "used_conf.txt"
• Visualization of the tree & the plan selections
