Постройке транзитивные замыкания для следующих бинарных отношений

Solution

The image shows a directed graph representing a binary relation. To construct the transitive closure of this binary relation, you need to add edges that represent all implied relationships (i.e., if aba \to b and bcb \to c, you must include aca \to c).

Step-by-Step Construction of Transitive Closure:

  1. Analyze the Existing Relation:

    • aba \to b
    • bcb \to c
    • ada \to d
  2. Find Indirect Relations:

    • Since aba \to b and bcb \to c, add aca \to c.
    • ada \to d exists directly, so no additions are needed for dd.
    • No further indirect relations are derivable.
  3. Final Transitive Closure: Add any missing edges derived in step 2. The full set of edges will include:

    • aba \to b
    • bcb \to c
    • aca \to c (added)
    • ada \to d

The transitive closure graph includes all original edges plus the implied edge aca \to c.

Would you like me to visualize the updated graph or provide additional details?
