  2. Partially ordered set - Wikipedia

    en.wikipedia.org/wiki/Partially_ordered_set

    Conversely, a strict partial order < on may be converted to a non-strict partial order by adjoining all relationships of that form; that is, := < is a non-strict partial order. Thus, if ≤ {\displaystyle \leq } is a non-strict partial order, then the corresponding strict partial order < is the irreflexive kernel given by a < b if a ≤ b and a ...

  3. Partial-order planning - Wikipedia

    en.wikipedia.org/wiki/Partial-order_planning

    A partial-order planner is an algorithm or program which will construct a partial-order plan and search for a solution. The input is the problem description, consisting of descriptions of the initial state, the goal and possible actions. The problem can be interpreted as a search problem where the set of possible partial-order plans is the ...

  4. Partition of a set - Wikipedia

    en.wikipedia.org/wiki/Partition_of_a_set

    This "finer-than" relation on the set of partitions of X is a partial order (so the notation "≤" is appropriate). Each set of elements has a least upper bound (their "join") and a greatest lower bound (their "meet"), so that it forms a lattice , and more specifically (for partitions of a finite set) it is a geometric and supersolvable lattice.

  5. List of order structures in mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_order_structures...

    Preorders, a generalization of partial orders allowing ties (represented as equivalences and distinct from incomparabilities) Semiorders, partial orders determined by comparison of numerical values, in which values that are too close to each other are incomparable; a subfamily of partial orders with certain restrictions

  6. Partitive - Wikipedia

    en.wikipedia.org/wiki/Partitive

    In linguistics, the partitive is a word, phrase, or case that indicates partialness. Nominal partitives are syntactic constructions, such as "some of the children", and may be classified semantically as either set partitives or entity partitives based on the quantifier and the type of embedded noun used.

  7. Weak ordering - Wikipedia

    en.wikipedia.org/wiki/Weak_ordering

    A total order is a total preorder which is antisymmetric, in other words, which is also a partial order. Total preorders are sometimes also called preference relations . The complement of a strict weak order is a total preorder, and vice versa, but it seems more natural to relate strict weak orders and total preorders in a way that preserves ...

  8. Happened-before - Wikipedia

    en.wikipedia.org/wiki/Happened-before

    This involves ordering events based on the potential causal relationship of pairs of events in a concurrent system, especially asynchronous distributed systems. It was formulated by Leslie Lamport. [1] The happened-before relation is formally defined as the least strict partial order on events such that:

  9. Event structure - Wikipedia

    en.wikipedia.org/wiki/Event_structure

    In mathematics and computer science, an event structure describes sequences of events that can be triggered by combinations of other events, with certain forbidden combinations of events. Different sources provide more or less flexible mathematical formalizations of the way events can be triggered and which combinations are forbidden.
