Correct . But since you can ' t estimate cost to finish in a maze where both finish and your distance from it are unknown , hn 0 or probably some nonsense value in OP ' s case , but should be 0 and this reduces to Dijkstra ' s . But since the edges have no weight , it ' s BFS . Which you ' d need to use anyway since you don ' t know the destination . <| sep |> This is really cool stuff . As an FYI for anyone who , like me , is hearing Fishmans for the the first time , there is an older LTM post with more info on the band <| sep |> I ' m guessing it was they talked about . <| sep |> Heh , one of the guys I play with will just leave if someone tries Lux support . Makes me laugh every time . <| sep |> Lorent suspected that Beron knew something . After all , the Hand of the King was responsible for singlehandedly keeping the Lord of Dragonstone from the crown , and to assume otherwise would have been naive and foolish but to hear the words come out of Alyn Baratheon ' s mouth . It put things into perspective . Lorent fell silent , his cold grey eyes turning the color of steel . Beron Baratheon knows about your gambit with Orys . He knew about the papers , about Orys . Though he was wrong about the forgery , Lorent was no fool , and knew no one would ' ve believed his claims regardless , truthful as they were . There had been a slight chance he could sway the lords before , but now armed with Lyonel ' s accusations and this knowledge , Lorent ' s credibility was shot . But how ? How did he know ? He and the Lord Commander had been so careful . You did the right thing , coming to me with this , Lord Baratheon . The blood of House Tyrell runs through us both we should rise together , as family . Let us speak now as kin . Please , my lord , have a seat , Lorent said , motioning to a chair . Before we proceed , I must know what else does the prince know ? Is there a spy in my ranks ?
