WebSep 13, 2024 · Consequently, we require a theoretical framework for modeling time-varying graphs. One possibility would be to consider a mathematical graph model with time-varying parameters (assumed to be random variables) that generates the network. Suppose we identify G-causality between the graph models' parameters. WebIt is well-known that if ω = ω ( n) is any function such that ω → ∞ as n → ∞, and if p ≥ ( log n + ω) / n then the Erdős–Rényi random graph G ( n, p) is asymptotically almost surely connected. The way I know how to prove this is (1) first counting the expected number of components of order 2, 3, …, ⌊ n / 2 ⌋, and seeing ...
