Greedy maximal independent sets via local limits

M Krivelevich, T Mészáros, P Michaeli… - Random Structures …, 2024 - Wiley Online Library
The random greedy algorithm for finding a maximal independent set in a graph constructs a
maximal independent set by inspecting the graph's vertices in a random order, adding the …

[HTML][HTML] Asymptotic optimality of degree-greedy discovering of independent sets in configuration model graphs

M Jonckheere, M Sáenz - Stochastic Processes and their Applications, 2021 - Elsevier
Finding independent sets of maximum size in fixed graphs is well known to be an NP-hard
task. Using scaling limits, we characterise the asymptotics of sequential degree-greedy …
