This script computes APLS (Average Path Length Similarity) and TOPO (Topology) metrics for road network graph predictions in parallel.

# Navigte to the optimized APLS directory
cd metrics/optimized_apls/

# Initialize Go module (first time only)
go mod init apls

# Install required dependencies
go get github.com/dhconnelly/rtreego@latest

./apls_topo_parallel.sh <gt-dir> <pred-dir> <result-dir> <n-parallel-apls> <n-parallel-topo>

• gt-dir: Ground truth graph pickle directory
• pred-dir: Parent directory containing graph folder
• result-dir: Output directory for results
• n-parallel-apls: Number of parallel processes for APLS (e.g., 8, 16, 32)
• n-parallel-topo: Number of parallel processes for TOPO (e.g., 16, 36, 48)

Note: set n-parallel-apls and n-parallel-topo to ≤ number of CPU cores
