These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.First of all, there is needed to outline some aspects involving problems belonging to NP (NP-Hard) class. As a parenthesis, NP stands for nondeterministic polynomial time algorithm which refers to the fact of discovering a nondeterministic Turing machine able to solve the problem in cause within a polynomial number of discovering nondeterministic movements.
Usually the pattern for NP has two steps: “guessing” solution and proving correctness....
