Writing a simple agent

Define an Agent with Beliefs, Goals, and Plans​

In JaKtA, an agent consists of:

  • Beliefs: Information about the world.
  • Goals: States or objectives the agents wants to achieve.
  • Plans: Sequences of actions that allow the agent to fulfill goals.

Hello World written in JaKtA​

This is a Hello World agent written with JaKtA syntax, printing the string "Hello, World!" to the console.

Create a file in the source folder of your gradle project (i.e. src/main/kotlin) named HelloAgent.kt, containing:

fun main() {
    mas {
        agent("myAgent") {
            goals {
                achieve("sayHello")
            }
            plans {
                +achieve("sayHello") then {
                    execute("print"("Hello, World!"))
                }
            }
        }
    }.start()
}

Run the system​

Now, run your program using:

./gradlew run

You should see the following output:

[myAgent] Hello, World!
