Computation Theory

Definition

Computation theory is a branch of computer science and mathematics that studies the nature of computation and the capabilities of computational systems. It examines what can be computed, how efficiently computations can be performed, and the limits of computation. This field is crucial in understanding the mechanisms behind learning and adaptation, particularly as they relate to synaptic plasticity and how information is processed in neural networks.
