Explanation of Solution
Modifying the AND-OR-GRAPH-SEARCH
- Check the figure S4.2 for the modified algorithm. When the OR-SEARCH cycles back to a state on “path” it returns a token “loop”. This means to loop back to the most recent time this state was reached along the path to it.
- There is sufficient information for later processing or a modified implementation to replace these with labels since the “path” is implicitly stored in the returned plan...

For the purpose of this exercise,we consider the nodes given and labeled,say,asAlice ,Bob,...... The graph consisting of a single edge connecting Alice and Bob is different from the graph consisting of a single edge connecting Eve and frank.)

What he seeks is a storage scheme such that goods that cannot be located at the same place are indeed separated. Provide a graph model to solve this problem. Do not write details of any algorithms. Simply describe your graph vertices, edges, and the classic graph theory problem that is useful for the design of the storage scheme here.arrow_forward

As an input, we have: All people - set named AP Set of people, that has to sit together - set named ST Set of people, that can't sit together - set named NST Number of tables - named NT Number of seats at the table - named NS Relation between elements of sets NT and NP is binary ireflexive. Prove, that out problem P is NP-complete problem. Reduce from Graph Coloring Problem to our P problem. I think, we have to construct a Turing machine working in polynomial time (there is no need to construct, just describe the working process of Touring machine). Also describe the reduction function. In my opinion, output should be string <AP>/<ST>/<NST>/<NT>/<NS>. The number of tables NT should be determined from graph, also the number of seats at the table NS. That's what I think.
