# Apply a state preprocessor with spec given by the "model" config option # (like other RL algorithms). This is mostly useful if you have a weird # observation shape, like an image. Auto-enabled if a custom model is set. "use_state_preprocessor": False, # Postprocess the policy netwo...
Multi-objective bi-level optimization(MOBLO) addresses nested multi-objective optimization problems common in a range of applications. However, its multi-objective and hierarchical bi-level nature makes it notably complex. Gradient-based MOBLO algorithms have recently grown in popularity, as they ...

There are two main types of optimization algorithms: exact and heuristic/stochastic methods [1]. Stochastic methods are preferred over exact methods as they are approximate methods and can provide near-optimal solutions with less computational effort [1]. In real-world problems like machine learning...
The most generic ones are: Genetic Algorithm, which simulates Darwin’s theory of evolution [7], Simulated Annealing (SA) algorithm, that is developed from the thermodynamic process [8], Particle swarm optimization (PSO) algorithms, which simulate the behaviour of fish school or bird flock [9...
