Flötteröd, Gunnar; Bierlaire, Michel - In: Transportation Research Part B: Methodological 48 (2013) C, pp. 53-66

We consider the previously unsolved problem of sampling paths according to a given distribution from a general network. The problem is difficult because of the combinatorial number of alternatives, which prohibits a complete enumeration of all paths and hence also forbids to compute the...

Investigating rare events by transition interface sampling

Moroni, Daniele; Erp, Titus S. van; Bolhuis, Peter G. - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 1, pp. 395-401

We briefly review simulation schemes for the investigation of rare transitions and resume the recently introduced transition interface sampling, a method in which the computation of rate constants is recast into the computation of fluxes through interfaces dividing the reactant and product state.
