The Elementary Path Problem: A DP Solution
can be computed as 1274 + 874 + 779 + 885 = 3812. Since the number of possible paths in this particular network is equal to 18 (= 2 × 3 × 3), the total computational effort of a complete enumeration is not unacceptable. However, as the number of cities in the network increases, the number of possible paths will grow very rapidly, making a complete enumeration prohibitively time consuming. It is...

An Elementary Boundary Value Problem
IT is intuitively obvious that if a simple continuous curve is given in the (x, 2/)-plane, and a continuous distribution of values along the curve, there will exist functions of x and y which are continuous in both variables together, and which take on the prescribed values along the curve. It is the purpose of the present note to give an analytic proof of this fact, by elementary means, and, i...
متن کاملElementary solution to the time-independent quantum navigation problem
A quantum navigation problem concerns the identification of a timeoptimal Hamiltonian that realises a required quantum process or task, under the influence of a prevailing ‘background’ Hamiltonian that cannot be manipulated. When the task is to transform one quantum state into another, finding the solution in closed form to the problem is nontrivial even in the case of time-independent Hamilton...
