Transformation Of Graph Dse Exercise ~repack~ (2026 Update)

Transformation of Graphs: Exercise Report

Introduction

In this exercise, we explored the transformation of graphs, which is a fundamental concept in mathematics and computer science. Graph transformations involve modifying the structure of a graph while preserving its essential properties. This report summarizes our findings and insights gained from completing the exercise.

Objective

The objective of this exercise was to apply various graph transformation techniques to a given graph, denoted as Graph DSE, and analyze the resulting graphs.

Graph DSE: Initial Graph

The initial graph, Graph DSE, consisted of:

• 5 nodes (A, B, C, D, E)
• 6 edges (AB, BC, CD, DE, EA, AC)

Transformation Techniques

We applied the following transformation techniques to Graph DSE:

1. Node Renaming: Renamed node C to F.
2. Edge Addition: Added a new edge between nodes B and D.
3. Edge Deletion: Deleted edge EA.
4. Node Merging: Merged nodes A and E into a single node, AE.
5. Node Splitting: Split node AE into two separate nodes, A and E.

Transformed Graphs

After applying each transformation technique, we obtained the following graphs: transformation of graph dse exercise

1. Graph DSE (Node Renaming):
   • Nodes: A, B, F, D, E
   • Edges: AB, BF, FD, DE, EA, AF
2. Graph DSE (Edge Addition):
   • Nodes: A, B, C, D, E
   • Edges: AB, BC, CD, DE, EA, AC, BD
3. Graph DSE (Edge Deletion):
   • Nodes: A, B, C, D, E
   • Edges: AB, BC, CD, DE, AC
4. Graph DSE (Node Merging):
   • Nodes: AE, B, C, D
   • Edges: AEB, BC, CD, DE, AEC
5. Graph DSE (Node Splitting):
   • Nodes: A, E, B, C, D
   • Edges: AB, BC, CD, DE, EA, AC

Analysis and Insights

The transformation techniques applied to Graph DSE resulted in different graphs, each with its own properties. The node renaming transformation did not change the graph's structure, while the edge addition and deletion transformations modified the graph's connectivity. The node merging and splitting transformations changed the graph's node structure.

Conclusion

In this exercise, we successfully applied various graph transformation techniques to Graph DSE and analyzed the resulting graphs. The transformations demonstrated the flexibility and power of graph manipulation, which is essential in many applications, such as network analysis, data mining, and software engineering.

Recommendations

• Further explore other graph transformation techniques, such as graph rewriting and graph composition.
• Apply graph transformation techniques to real-world problems, such as network optimization and software refactoring.
• Investigate the use of graph transformation in machine learning and artificial intelligence.

4. Check Invariant Points

Points that remain unchanged under transformation can help verify your answer. E.g., reflection over x-axis: points on x-axis stay put.

| New equation | Meaning | |--------------|---------| | (y = f(x-a) + b) | Right a, up b | | (y = -f(x)) | Reflect in x-axis | | (y = f(-x)) | Reflect in y-axis | | (y = k f(x)) | Vertical stretch (k>1) / compress (0<k<1) | | (y = f(ax)) | Horizontal compress (a>1) / stretch (0<a<1) | | (y = f(ax + b)) | First factor: (a(x + b/a)) → compress by (1/a), then shift left (b/a) |

Order: Horizontal stretch/compress → Horizontal shift → Vertical stretch/compress → Reflection → Vertical shift.
