Abstract
With the advent of the high speed digital computer, many
problems heretofore considered unsolvable for all practical
purposes are now well within the reach of the applied mathematician.
One such problem is the routing of a shin through
a time dependent ocean wave field, from one point on the
earth's surface to another, so as to minimize a cost function
of the form g(x,y,t,u). This paper considers a numerical solution to the above
problem. The technique to be employed is known as the method
of steepest ascent and is attributed to Arthur E. Bryson and
Walter F. Denham [1]. Although the computer program as given
in the Appendix is written specifically for a VC2AP3 class
vessel operating in a described area of the North Pacific
Ocean, it can be readily modified to accommodate any type
vessel operating in the Northern Hemisphere.
