As mentioned previously, the mass of the vehicle is computed for each point<br />
<strong>and</strong> is stored along with the control that was needed to get there.<br />
The second decision must come from a wealth of possibilities. If an<br />
approach similar to the shortest distance problem is taken (where the only<br />
permissible transitions eminate in rays from the initial point of the<br />
particular transition), a reasonable set of transitions for each point is<br />
obtained. To give the reader an idea of the number of points which are<br />
possible, the following table was constructed to show this set of points<br />
by using a shorth<strong>and</strong> notation for convenience (where @ = 0, Xi, 2X$.<br />
