:::::::: I was referring to the order of the blocks (and the manner in which they are chosen, and then marked for non-participation for later choices).   I'm not sure what you mean by arranging the letters.   The whole point is to arrange the letters [here and ''Scrabble'' (R)] to spell words.   As for what you saw on Wiki, I can only surmise what WIKI ''exactly'' describes;   I think the Wiki article pretty much describes the methodology of the initial attempt of the what the REXX version 1 program did (albeit the original REXX version 1 algorithm didn't go deep enough to find a solution for some other later examples talked about, which made it an ineffective and an incorrect algorithm).   There are other definitions of ''greedy algorithm'', but I don't to spend time and effort to see if those definitions apply to the initial REXX version 1 attempt, one reason is the initial REXX version 1 program is defunct.   The initial REXX attempt could spell   '''bbaa'''   but not   '''abba'''.   The current REXX version 1 can   (using the pool of blocks:   '''AC AC AB AB'''   in any order). -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 00:54, 13 January 2014 (UTC)
