Approximate -hop neighborhoods on incremental graphs: An efficient lazy approach
Luca Becchetti, Andrea Clementi, Luciano Gualà +3
In this work, we propose, analyze and empirically validate a lazy-update approach to maintain accurate approximations of the -hop neighborhoods of dynamic graphs resulting from…
