    1. The formulation of a wicked problem is the problem! The process of formulating the problem and of conceiving a solution (or re-solution) are identical, since every specification of the problem is a specification of the direction in which a treatment is considered.

      Context of the problem space and of potential soultions is also important here. Understanding the context also points the way toward participatory design and critical reflective thinking.

    2. By now we are all beginning to realize that one of the most intractable problems is that of defining problems (of knowing what distinguishes an observed condition from a desired condition) and of locating problems (finding where in the complex causal networks the trouble really lies). In turn, and equally intractable, is the problem of identifying the actions that might effectively narrow the gap between what-is and what-ought-to-be.

      Defining problems to solve and gaps to narrow remains a challenge in public policy, as well as science,

    1. For the task is not one of calculating the effi-ciency of different possible means toward an already determined end. It often involves,rather, deliberation about the end itself – about what would count as a satisfactory,or at least not entirely unacceptable, outcome to a particular “case.” And it may onlybe by action – and not, in the end, by any purely analytic process – that thisdeliberation can really be followed through.

      Deeply insightful,

    1. Boolean satisfiability problem

      This is just one specific type of the classes of satisfiability problems (a.k.a. search problems).

      Other related problems include: Linear equation satisfiability, Linear inequality satisfiability, 0-1 integer linear equation satisfiability.

      Given the current context (of search problems), all the above are known as NP problems in general (with the observation, that the classic definition of NP limited the scope to only YES-NO problems).

      One can think of search problems as "one of many ways of characterizing the set of problems that form the basis of the study of intractability". Other ways include viewing such problems through the lenses of decision problems or optimization problems. In other words, problems in any of the aforementioned types can be translated between (or more formally, reduced to) each other with relative ease.

    1. from which dogs derive

      This entire sentence should be selected, but when I try, I don't pop up an annotation box. It seems to be the first four words (gray wolf (Canis lupus) that is the problem. Encountered something similar below.
