  1. CAD Contest 2013Problem E: Region Query Ming-Ter Kuo and Abner Huang Synopsys Taiwan Limited Sponsor: Minister of Education, Republic of China (Taiwan)

  2. Outline • Introduction • Contest problem • Benchmark cases • Evaluation metrics • Contest results

  3. Introduction – Region Query • Searching for objects that intersect a specified window area in two-dimensional space is commonly referred to as region query.

  4. Region Query Commands • Five types of region query commands • Find the polygons contained by a window. • Find the polygons interacting with a window. • Find the polygons interacting with a window that do not overlap with others. • Find the polygons whose area are less than a given number. • Find the percentage (density) of the given window area that are covered by polygons.

  5. Contest Problem • Input data: polygons described by a list of points with two dimensional coordinates. • Query commands: five types of commands with a specified window or area constraint. • FIND_INSIDE • FIND_INTERACT • FIND_NO_OVERLAP • FIND_AREA_LESS_THAN • FIND_DENSITY_INSIDE

  6. Contest Problem • Output: report the number of polygons for polygon queries. For the density query, report the percentage. • Example: • FIND_INSIDE 58 106 137 174 • 10 • FIND_INTERACT 58 106 137 174 • 12 • FIND_NO_OVERLAP 58 106 137 174 • 8 • FIND_AREA_LESS_THAN 20 • 4 • FIND_DENSITY_INSIDE 58 106 137 174 • 12.09%

  7. Benchmark Cases • Each case is run with 500 queries (100 queries per type).

  8. Evaluation Metrics • Correctness: 50% • Score is calculated by the number of correct answers. • Each case must have at least 80% correct answers. • Runtime: 40% • Score is calculated by a normalized runtime factor among all contest programs. • Cutoff time for each case is 1 hour. • Memory usage: 10% • Score is calculated by a normalized peak memory factor among all contest programs.

  9. Team Statistics • Finalists are the teams who have program capability that meets the correctness and runtime criteria.

  10. Case 1: p126430

  11. Case 2: p159909

  12. Case 3: p180378

  13. Case 4: p237960

  14. Case 5: p582110

  15. Case 6: p423850

  16. Total Rank Values • The team with the lowest total rank value wins the contest.
