gltl | The compiler DomainGenerator code

gltl is a Java library. gltl has no bugs, it has no vulnerabilities and it has low support. However gltl build file is not available. You can download it from GitHub.

The compiler DomainGenerator code is src/gltl/compiler/GLTLCompiler.java. The compiler can take any arbitrary BURALP domain as input for the environment domain (see SimpleDemo to see it in action). Currently, the compiler does not actually compile a GLTL formula and instead uses Min's hard coded task transition dynamics for formula's specified by the numebr 1-4. However, the GLTLCompiler class is designed around the notion that it will be extended so that it takes as input an arbitrary GLTL formula as well as a mapping from symbols in the formula to environment state propositional functions that can be evaluated and then will generate the TASK MDP accordingly. Primarily, this will require rewriting the method getTaskTransitions(State s, State nextEnvState), which should return a distribution over the next task MDP state values (and again, is currently hardcoded for formulas 1-4). I imagine that the generateRewardFunction() and generateTerminalFunction() methods will also need to be defined so that they are arbitrary to any GLTL formula that is input. The previous example code that Min wrote is also included in this repo. It is in the file src/gltl/prototype/EnvironmentMDP.java.
