This code creates a binary quadratic model using the dimod library and adds an objective function to each edge. The graph is then created with 1 points of edges, which can be used for costing between two connections in parallel by adding interaction

Binary Quadratic Model for Graph Optimization

Preview:
import dimod

# Define the graph and binary variables
graph = {('A', 'B'), ('A', 'C'), ('B', 'C'), ('B', 'D'), ('C', 'D')}
binary_variables = {'A', 'B', 'C', 'D'}

# Create a binary quadratic model (BQM)
bqm = dimod.BinaryQuadraticModel.empty(dimod.BINARY)

# Add the objective function
for u, v in graph:
    # Add the cost of edge connection
    bqm.add_interaction(v, v, 1)

# Print the binary quadratic model
print(bqm)

💡 Smart Description This code creates a binary quadratic model using the dimod library and adds an objective function to each edge. The graph is then created with 1 points of edges, which can be used for costing between two connections in parallel by adding interaction
The code snippet defines a graph and binary variables, then creates a binary quadratic model (BQM) using the dimod library. It adds the objective function to the BQM, which assigns a cost of 1 to each edge connection in the graph
