a- +‎ cyclic


  • The basic model creates acyclic graphs because old nodes never link to new nodes.

    The Weasel Thread

  • In later versions of the model, some rewiring was also introduced to make sure that the graph that is generated is not acyclic.

    The Weasel Thread

  • There was the handmade paper phase, the hand-bound journal phase, the acyclic paint phase, the scrap booking phase, the Fimo clay phase, the beading phase, the homemade head band phase, the hemp jewelry phase, ACK!

  • The question is, using the current algorithm, will the final acyclic graph be different if this cycle resolution was done ahead of time?

  • Researchers report in the recent issue of Industrial & Engineering Chemistry Research that they've found a way to coat Kevlar with a potent substance, acyclic N-Halamine, that can kill infectious agents, including bacteria, viruses and the spores that cause anthrax.

  • They use directed acyclic graphs and associated probability distributions to construct causal models.

    Causal Decision Theory

  • In directed acyclic graphs, nodes doubly represent variables with a range of values and occurrences with a range of possibilities, and links doubly represent structural equations and causal parenthood.

    The Metaphysics of Causation

  • Reply obviously standards must be developed adn adhered to in order to improve the disjointed tracking of of the non primary secondary tertiary etc conversation graph. i'm amazed we've suffered through this primitive system so long already. we need multi-directional acyclic graph mechanisms that span trackbacks AND comments. wake up people! dav

  • Since these sets must be acyclic, i.e., no element in a causal set can causally precede itself, CTCs are ruled out a priori.
