CloudFlare suffered a massive security issue affecting all of its customers, including Rosetta Code. All passwords not changed since February 19th 2017 have been expired, and session cookie longevity will be reduced until late March.--Michael Mol (talk) 05:15, 25 February 2017 (UTC)

Weather Routing

From Rosetta Code
Weather Routing is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

The weather routing problem has the following parts:

  • a predicted surface wind direction and speed, at increments of longitude, latitude, and time
  • an expected surface current direction and speed, at increments of longitude, latitude, and time
  • 'polar data' describing maximum speed of a sailboat at points of sail for a given speed of wind over water
  • regions for sailing (the open ocean) and not (the land, shallows, restricted areas, etc.)
  • a starting location and time, and a destination

Given the above information and a specific path, progress and arrival time are determined. The weather routing problem, conversely, is to determine the path which results in the earliest arrival time.
