Overview of Running an Experiment
- Specify your operations in operations.py.
- Specify a list of operations to use in operations_list.py.
- Run program_synthesis.py to synthesize programs with your list of operations.
- Specify an experperiment in test_synthesized_programs_experiments.py.
- Run test_synthesized_programs.py to search over your program space.
- Use scripts/analyze_synthesized_programs.py to analyze your results.
datastructures.py: The datastructures manipulated by program operations.
executor.py: Executes a Program object.
find_duplicate_programs.py: Takes a list of programs and finds / prunes duplicates by testing each program on a fake environment and looking at the output signature.
gridworld_environments.py: Our gridworld environments.
internal_rewards.py: The module that runs intrinsic curiosity programs and reward combiner programs.
operations_list.py: A configuration file that specifies the operations that can appear in different program classes
operations.py: The operations that are composed to create a program.
predict_performance.py: The regressor that predicts program performance from its
predict_performance_experiments.py: A configuration file for experimenting with performance regressors.
program.py: The core abstraction of a program, represented by a DAG of operations**.
program_synthesis.py: The search module that synthesizes programs.
program_types.py: The types that operations in our language can output.
run_agent.py: The module that runs an agent in an environment.
search_programs.py: The module that searches over a program space, given a list of programs, an environment, and a program selection metric.
search_programs_experiments.py: A configuration file for simulating program searches.
simulate_search.py: A module that simulates searching through programs.
test_synthesized_programs.py: The module that takes a set of synthesized programs and initiates a search over them.
test_synthesized_programs_experiments.py: The configuration file for testing / searching over programs.\
