Codes for IJCAI 20 and some data exploration. Below is summary of key modifications that I made to the provided codes

• Added random seeds in any parts of codes that generate randomness (data generation, initial points of deep model,..).

• Kept a log to track different metrics, e.g sum of absolute magnitude of violations, number of violated constraints.

• There was a bug in model_3, that made the model_3 could not take into account of Lagrangian term in updating model's parameter. I corrected that.

• Revised structure of the constructor __init__ function a bit, and add grid search opt to models.

• Check IJCAI/src/run_experiments.py
