Q30 · Combinatorial Strategy

Q30 · Combinatorial Strategy

Several chess pieces are placed on a board, each able to move horizontally or vertically to adjacent empty squares. What is the minimum number of moves needed to arrange all pieces along a diagonal?
Solution Approach:
This is an optimization problem. First analyze the target state (diagonal arrangement), then work backwards to find the shortest path from each piece to its target position. Use Manhattan distance to calculate individual move counts, then optimize globally to avoid conflicts. The sum gives the minimum total moves.

05 2023 Australian AMC Study Guide

Targeted preparation tips by topic, based on this year’s difficulty and focus areas

The 2023 Australian AMC had an overall difficulty of Medium. Prepare in order — secure the high-frequency and foundational areas first, then break through the advanced topics — with timed practice on this year’s papers.

Frequent

Combinatorics

a high-frequency area this year — prioritise it and drill Permutations, inclusion-exclusion principle, counting strategies for reliable marks.

Core

Logical Reasoning

a core scoring area — master Propositional logic, proof by contradiction, constructive proofs thoroughly.

Foundation

Equation Modeling

a foundational area — lock in Word-to-equation problems, multi-variable systems, inequalities to avoid easy losses.

Must-Know

Plane Geometry

appears almost every year — build a fixed method for Similar triangles, Pythagorean theorem, circle properties.

Advanced

Divisibility & Remainders

key to high scores — once the basics are solid, focus on Division with remainder, introduction to Chinese Remainder Theorem.

Innovative

Intro to Graph Theory

an innovative direction this year — get familiar with the basics of Path counting in simple graphs, connectivity analysis.

This year’s featured / final problem direction is “Q30 · Combinatorial Strategy” — practise this problem type specifically and build complete analysis and write-up habits.
