1. A method of sports play retrieval, comprising: (7) (6)

receiving positional data, across an interval window, comprising a respective agent trajectory for each of a plurality of agents during the interval window;

partitioning the interval window into a plurality of frames;

at each of the plurality of frames, calculating a cost of assigning a role to each agent of the plurality of agents based on one or more exemplar formations;

determining a formation by assigning a role to each agent based on the calculated cost;

comparing each frame of the plurality of frames of the formation to a corresponding frame of a stored formation, by calculating a distance between a position of each assigned role in the frame and a position of a corresponding role in the stored formation; and

generating, based on the comparisons, a list of stored formations that are similar to the formation.

2. The method of claim 1, wherein receiving the positional data, across the interval window, comprising the respective agent trajectory for each of the plurality of agents during the interval window, further comprises: (0) (2)

3. The method of claim 1, wherein receiving the positional data, across the interval window, comprising the respective agent trajectory for each of the plurality of agents during the interval window, further comprises: (1) (1)

receiving a plurality of measured agent locations from an existing sports activity.

4. The method of claim 3, further comprising: (0) (2)

5. The method of claim 1, further comprising: (0) (3)

6. The method of claim 1, further comprising: (0) (1)

7. The method of claim 1, wherein receiving positional data for the formation, across the interval window, comprising the respective agent trajectory for each the plurality of agents during the interval window, further comprises: (0) (2)

8. The method of claim 1, further comprising: (0) (2)

9. The method of claim 1, further comprising: (0) (2)

10. A non-transitory computer-readable storage medium including instructions that, when executed by a processor, cause the process to retrieve sports plays, by performing an operation comprising: (7) (6)

receiving positional data, across an interval window, comprising a respective agent trajectory for each of a plurality of agents during the interval window;

partitioning the interval window into a plurality of frames;

at each of the plurality of frames, calculating a cost of assigning a role to each agent of the plurality of agents based on one or more exemplar formations;

determining a formation by assigning a role to each agent based on the calculated cost;

generating, based on the comparisons, a list of stored formations that are similar to the formation.

11. The non-transitory computer-readable storage medium claim 10, wherein receiving the positional data, across the interval window, comprising the respective agent trajectory for each of the plurality of agents during the interval window, further comprises: (0) (2)

12. The non-transitory computer-readable storage medium of claim 10, wherein receiving the positional data, across the interval window, comprising the respective agent trajectory for each of the plurality of agents during the interval window, further comprises: (1) (1)

receiving a plurality of measured agent locations from an existing sports activity.

13. The non-transitory computer-readable storage medium of claim 12, further comprising: (0) (2)

14. The non-transitory computer-readable storage medium of claim 10, further comprising: (0) (3)

15. The non-transitory computer-readable storage medium of claim 10, further comprising: (0) (1)

16. The non-transitory computer-readable storage medium of claim 10, wherein receiving positional data for the formation, across the interval window, comprising the respective agent trajectory for each of the plurality of agents during the interval window, further comprises: (0) (2)

17. The non-transitory computer-readable storage medium of claim 10, further comprising: (0) (2)

18. The non-transitory computer-readable storage medium of claim 10, further comprising: (0) (2)

19. A computing system, comprising: (1) (2)

a memory that is configured to store instructions for a program; and

a processor that is configured to execute the instructions for the program to retrieve sports plays, by performing an operation comprising: receiving positional data, across an interval window, comprising a respective agent trajectory for each of a plurality of agents during the interval window;

partitioning the interval window into a plurality of frames;

at each of the plurality of frames, calculating a cost of assigning a role to each agent of the plurality of agents based on one or more exemplar formations;

determining a formation by assigning a role to each agent based on the calculated cost;

generating, based on the comparisons, a list of stored formations that are similar to the formation.

20. The computing system of claim 19, wherein receiving the positional data, across the interval window, comprising the respective agent trajectory for each of the plurality of agents during the interval window, further comprises: (0) (2)
