+# Graph Algorithms: Assessment Highlights
+
+A collection of graph problems that test deep understanding rather than memorization.
+
+## The Bridge Detection Variant
+
+Find all edges whose removal increases the number of triangles in the graph.
+
+### Solution Approach
+
+Counter-intuitively, we need to count triangles that share exactly one edge with the candidate. The algorithm runs in O(m√m) time using careful enumeration.
+
+## Shortest Path with Wildcards
+
+Given a graph where some edge weights are variables, find assignments that minimize the longest shortest path.
+
+### Key Insight
+
+This reduces to a linear programming problem with interesting structure. The dual interpretation reveals connections to network flow.
+
+## Teaching Through Problems
+
+These problems help students see beyond standard algorithms to underlying principles.
