K> the textbook under the graph theory Is necessary, something is desirable new enough that included results of researches not only 30-year-old prescription, but also that has been described about 5 years ago. Looking in what direction to you it is necessary. Columns is classics. It practically does not change for a long time already. Another matter - applications. For example, usage of graphs in compilation - here Kasyanov and Yevstigneyev's monography of 1500 pages, a pancake!). In wrote the textbook on usage of graphs in public affairs. For example, a choice, a coalition in parliament, etc. actively enough parallel algorithms on columns are considered. That is, all classical serial algorithms on columns - . Here it is possible to look at a series on supercomputers.
