Does anyone know of any analytic approximations for the relationship between the efficiency of either a) source/compression coding algorithms, b) channel/error-correction coding algos, or even c) rate-distortion curves *AND* their computational/Big-O complexity (time or space)?

Next was a weirdly fascinating talk on #quantum #ComputationalComplexity by Daniel Grier. Grier is able to prove that existing quantum computers can do certain tasks that are impossible for classical computers, albeit a narrow set https://www.youtube.com/watch?v=P81oJ5wZY20 (5/12)

Speaking of hashtags, I'm curious how the TCS community feels about making "complexity" searchable, given how overloaded that term is. #complexity is at least partially taken, #computationalcomplexity is super long. #TCScomplexity? More broadly speaking, any interest in making #TCS a thing?
