A configuration file is a json file with the following fields. We also provide sample configuration files.

• bug_dir: ABSPATH for saving found bugs.
• data_dir: ABSPATH for saving preprocessed data.
• eng_name: Target JS engine ("chakra", "v8", "moz", "jsc").
• eng_path: ABSPATH to the JS engine.
• max_ins: The maximum number of fragments to append.
• model_path: The path to the saved model to use for fuzzing.
• batch_size: The batch size to use for training.
• emb_size: The embedding dimension for each fragment.
• epoch: The maximum number of epochs for training.
• gamma: The multiplicative factor of learning rate decay.
• lr: The initial learning rate.
• momentum: The momentum factor for SGD.
• split_size: The size of each split. Montage splits each sequence into multiple sequences for training efficiency.
• weight_decay: Weight decay (L2 penalty).
• num_gpu: The number of GPUs to use for fuzzing.
• num_proc: The number of processes (cores) to use for fuzzing.
• opt: Additional options for executing a JS engine.
• seed_dir: ABSPATH to the directory containing seed JS files.
• timeout: Timeout for executing a JS code.
• top_k: The number of candidate fragments.
