Moderate -0.5 This is a standard Hungarian algorithm application question from D2, requiring systematic application of a well-defined procedure (row/column reduction, covering zeros, adjustments) to find optimal allocation. While it involves multiple steps, it's a routine algorithmic process with no conceptual insight or problem-solving required beyond following the taught method.
3 Four pupils, Wendy, Xiong, Yasmin and Zaira, are each to be allocated a different memory coach from five available coaches: Asif, Bill, Connie, Deidre and Eric. Each pupil has an initial training session with each coach, and a test which scores their improvement in memory-recall produces the following results.
