**MEUZZ** is a machine learning-based hybrid fuzzer which employs supervised machine learning for adaptive and generalizable seed scheduling -- a prominent factor in determining the yields of hybrid fuzzing. MEUZZ determines which new seeds are expected to produce better fuzzing yields based on the knowledge learned from past seed scheduling decisions made on the same or similar programs. MEUZZ's learning is based on a series of features extracted via code reachability and dynamic analysis, which incurs negligible runtime overhead (in microseconds). Moreover, MEUZZ automatically infers the data labels by evaluating the fuzzing performance of each selected seed.

**Differentiable Architecture Search** (**DART**) is a method for efficient architecture search. The search space is made continuous so that the architecture can be optimized with respect to its validation set performance through gradient descent.

MEUZZ: Smart Seed Scheduling for Hybrid Fuzzing

**D4PG**, or **Distributed Distributional DDPG**, is a policy gradient algorithm that extends upon the [DDPG](https://paperswithcode.com/method/ddpg). The improvements include a distributional updates to the DDPG algorithm, combined with the use of multiple distributed workers all writing into the same replay table. The biggest performance gain of other simpler changes was the use of $N$-step returns. The authors found that the use of [prioritized experience replay](https://paperswithcode.com/method/prioritized-experience-replay) was less crucial to the overall D4PG algorithm especially on harder problems.
