It looks like you've uploaded an image containing a math problem involving a graph and a question about the
maximum number of points that can be selected from the graph such that no two points are adjacent. However, I currently cannot view or analyze images directly.
To help you, please provide:
1. A
text description of the graph (e.g., coordinates of the points, how they're connected).
2. The exact
problem statement (e.g., "What is the maximum number of non-adjacent points that can be chosen?").
Alternatively, if you can describe the graph — for example, it's a line graph with points at specific coordinates and edges between consecutive points — I can guide you through solving it step by step.
For now, based on common problems of this type, here’s a general explanation:

🔍 Problem Type: Maximum Independent Set on a Graph
If the task is to select the
maximum number of points such that
no two are adjacent, this is known as finding the
maximum independent set.
In the case of a
path graph (a sequence of points where each point is connected only to its immediate neighbors), there's a well-known dynamic programming solution.
#### Example:
Suppose the graph is a path of 10 nodes:
`A — B — C — D — E — F — G — H — I — J`
We want to pick the maximum number of nodes such that no two are adjacent.
This is a classic DP problem:
- Let `dp[i]` = maximum number of non-adjacent nodes we can choose from the first `i` nodes.
- Recurrence:
`dp[i] = max(dp[i-1], dp[i-2] + 1)`
(Either skip node i, or take it and add to the best choice from i-2)
Base cases:
- `dp[0] = 0`
- `dp[1] = 1`
Then compute up to the last node.

✔ Solution Strategy:
1. List all points in order (say along x-axis).
2. Determine adjacency (usually consecutive points are connected).
3. Apply the DP algorithm above.
Let me know the details of your graph (coordinates, connections, etc.), and I’ll solve it exactly!
