TopicDynamic Programming
TypeDynamic programming maximin route
DifficultyStandard +0.3 This is a standard dynamic programming maximin route problem with a small network. It requires systematic tabulation following a well-defined algorithm taught in D2, with no conceptual tricks or novel insights—slightly easier than average since it's a direct application of a bookwork method with clear structure.
Spec7.01a Types of problem: existence, construction, enumeration, optimisation7.03b Algorithm awareness: uses and practical limitations7.03c Working with algorithms: trace, interpret, adapt

6 Set up a dynamic programming tabulation to find the maximin route from ( \(0 ; 0\) ) to ( \(3 ; 0\) ) on the following directed network. \includegraphics[max width=\textwidth, alt={}, center]{76486ad4-c00e-4e0b-9527-6f13f9222dbb-7_883_1323_390_411}
