Theory of Computation: Monotone Complexity and XOR-SAT Lower Bounds

This lecture delves into the theory of computation, focusing on monotone complexity and XOR-SAT lower bounds. It covers the concept of monotone circuits, the absence of negation gates, and the implications of monotone circuits in the P vs. NP problem. The instructor presents a new lower bound theorem related to XOR-SAT, showcasing the complexity of monotone circuits. Additionally, examples of monotone computations are provided to illustrate the concepts discussed. The lecture concludes with an overview of various topics in the field, such as optimization, learning theory, and proof complexity.
