Proof mining

In proof theory, a branch of mathematical logic, proof mining (or unwinding) is a research program that analyzes formalized proofs, especially in analysis, to obtain explicit bounds or rates of convergence from proofs that, when expressed in natural language, appear to be nonconstructive.^[1] This research has led to improved results in analysis obtained from the analysis of classical proofs.
