The image you uploaded appears to contain a map that shows an area marked with routes and some points of interest, possibly locations where activities or "plays" are located. To find a way to cross all the plays (presumably these are marked locations on the map), the goal could be interpreted as finding an optimal path that visits each of these marked points at least once, while minimizing the total distance or time taken. This is similar to solving the Traveling Salesman Problem (TSP) or a Chinese Postman Problem (CPP) depending on the exact setup.

Here’s a general approach you can use:

Steps to cross all points (Plays):

1. Identify the Nodes (Plays): First, determine the exact locations marked as plays (the specific points) on the map.
2. Map the Routes: Observe the network of roads or paths connecting these plays. These will act as your edges in a graph.
3. Optimize the Path:
   • If the task is to visit all the plays once, you are solving a Traveling Salesman Problem (TSP). You need to find the shortest route that visits all the plays.
   • If the task is to traverse every road at least once while visiting all the plays, then you're solving a Chinese Postman Problem (CPP), where the goal is to minimize the total length of the walk while covering all edges.
4. Calculate the Shortest Path: Depending on the number of points and paths, you can use algorithms such as:
   • Dijkstra's Algorithm for shortest paths between specific points.
   • Eulerian Path or Circuit algorithms for CPP, if all paths must be covered.

Would you like help identifying the plays and routes on the map, or would you prefer to proceed with a mathematical approach based on these steps?

Questions for you:

1. Are all the plays clearly marked on the map, or do you need help identifying them?
2. Is your goal to minimize the distance traveled between the plays, or is it important to cover all routes (roads)?
3. Are there any specific constraints like time or distance limits that you want considered?
4. Would you like a visual diagram of the solution?
5. Would you like more information on algorithms like TSP or CPP?

Tip:

If you want an algorithmic solution, breaking down the problem into nodes (plays) and edges (routes) first will make it easier to apply a mathematical model.
