The algorithm runs in O(m + Kn) time using O(K + m) space in DAGs with integer length arcs.
Also, our method could be used to sample over the space of DAGs using a Markov Chain Monte Carlo strategy.
We use Metropolis-coupled Markov Chain Monte Carlo (MC) methods [ 17] over the space of DAGs for the approximation of Eq.1.
'Several companies in what would become Silicon Valley benefited from the ambitious goals and budget largesse of the Apollo space program,' said Dag Spicer, the senior curator of the Computer History Museum, in Mountain View, Calif.
Score-based methods search the space of all possible DAGs to identify the network which maximizes a penalized likelihood function.
Unfortunately, owing to the restriction of the network structure to that of a directed acyclic graph (DAG), it is difficult to explore the space of possible network structures.
Geometric data structures: Doubly-connected edge lists, quad-edges, face lattices, trapezoidal maps, history DAGs, spatial search trees (a.k.a. range search), binary space partitions, visibility graphs.
Geometric data structures: Doubly-connected edge lists, quad-edges, face lattices, trapezoidal maps, conflict graphs, history DAGs, spatial search trees (a.k.a. range search), binary space partitions, quadtrees and octrees, visibility graphs.

We represent evolutionary relationships between a set of duplication blocks as a directed acyclic graph (DAG), and we formalize the evolutionary reconstruction problem as an optimization over the space of DAGs.
