    1. Assumption 6.4.

      \((i, j)\in A\iff (j, i)\in A\). We allow for arcs with zero capacity. For all single direction arc, the opposite direction arc on the graph is having a capacity of zero.

      I think this is essentially a residual graph on the zero flow, which is trivially feasible. Residual graph on the network is covered in the later part of the chapter (pg177).

    2. Assumption 6.5

      No parallel arcs.

    3. Assumption 6.3

      Doesn't contain a direction path with infinite capacity from source to node. (Makes sure that the problem is not unbounded)

    4. Assumption 6.2

      All capacities are nonnegative integers.

    5. Assumption 6.1

      The Network is Directed

    6. Assumption 4.4. The network is directed.

      Assumptions required for labeling algorithms, and non-directed edges can be reduced to parallel double edges.

    7. Assumption 4.2.
    8. Assumption 4.1.
    9. Assumption 4.3.

    1. It feels like « removing spring » is one of those unchallenged truths like « always remove Turbolinks » or « never use fixtures ». It also feels like a confirmation bias when it goes wrong.

      "unchallenged truths" is not really accurate. More like unchallenged assumption.

    1. In general, it is best to assume that the network is filled with malevolent entities that will send in packets designed to have the worst possible effect.

    1. Adam Kucharski. (2021, April 14). If populations are highly vaccinated, we’d expect a higher proportion of future cases to have been previously vaccinated (because by definition, there aren’t as many non-vaccinated people around to be infected). But what sort of numbers should we expect? A short thread... 1/ [Tweet]. @AdamJKucharski. https://twitter.com/AdamJKucharski/status/1382242089673617417

    1. You will be disrupted by this first issue. It is natural to expect relative references to be resolved against the .sass/.scss file in which they are specified (like in regular .css files).

    1. the proof: an entire page of results

      Is the author assuming that most people regard Google Searches as anything more than a result? Gospel? How many people have even a rudimentary understanding of page rank? Whose duty is it make sure they do?

    1. Among the most useful summaries I have found for Linked Data, generally, and in relationship to libraries, specifically. After first reading it, got to hear of the acronym LODLAM: “Linked Open Data for Libraries, Archives, and Museums”. Been finding uses for this tag, in no small part because it gets people to think about the connections between diverse knowledge-focused institutions, places where knowledge is constructed. Somewhat surprised academia, universities, colleges, institutes, or educational organisations like schools aren’t explicitly tied to those others. In fact, it’s quite remarkable that education tends to drive much development in #OpenData, as opposed to municipal or federal governments, for instance. But it’s still very interesting to think about Libraries and Museums as moving from a focus on (a Web of) documents to a focus on (a Web of) data.

    2. Anyone can say Anything

      The “Open World Assumption” is central to this post and to the actual shift in paradigm when it comes to moving from documents to data. People/institutions have an alleged interest in protecting the way their assets are described. Even libraries. The Open World Assumption makes it sound quite chaotic, to some ears. And claims that machine learning will solve everything tend not to help the unconvinced too much. Something to note is that this ability to say something about a third party’s resource connects really well with Web annotations (which do more than “add metadata” to those resources) and with the fact that no-cost access to some item of content isn’t the end of the openness.

    1. things that are true and things that are just have a natural tendency to prevail over their opposites,

      Enthymeme? Is this idea an assumption held by the public?
