Core concepts

Describe Slam concepts, what they mean, how they are used, etc.

Sets, relations and maps in slam

Fig. 33 A relation (blue lines) between two sets (ovals with red and green dots, as elements) and a map of scalar values (brown) on the second set.

Set

  • Taxonomy of set types (OrderedSet, IndirectionSet, Subset, static vs. dynamic)

  • Simple API (including semantics of operator[] and iterators )

  • Example to show how we iterate through a set

Relation

  • Relational operator (from element of Set A to set of elements in Set B)

  • Taxonomy:

    • Cardinality: Fixed vs Variable number of elements per relation

    • Mutability: Static vs. Dynamic relation

    • Storage: Implicit vs. Explicit (e.g. product set)

  • Simple API (including semantics of operator[] )

  • Three ways to iterate through a relations

    • Double subscript

    • Separate subscripts

    • Iterators

Map

  • Data associated with all members of a set

  • Simple API (including semantics of operator[] )
