description	Format and write Pareto frontier results to CSV file with proper rounding and column ordering.

Output File

Write results to: /root/pareto_frontier.csv

CSV Format

F1,delta,min_samples,epsilon,shape_weight

Column order (exactly as shown):

1. F1 — F1 score (float)
2. delta — Average Euclidean distance of matches (float)
3. min_samples — DBSCAN parameter (integer)
4. epsilon — DBSCAN parameter (integer)
5. shape_weight — Custom distance weight (float)

Rounding Requirements

• F1: Round to 5 decimal places
• delta: Round to 5 decimal places
• min_samples: Integer (no decimal)
• epsilon: Integer (no decimal)
• shape_weight: Round to 1 decimal place

Row Ordering

Sort rows by:

1. F1 (descending) — highest F1 first
2. delta (ascending) — lowest delta second (for ties in F1)

Example Format

F1,delta,min_samples,epsilon,shape_weight
0.75234,12.34567,5,12,1.2
0.74891,13.45678,6,14,1.3
0.72345,11.23456,4,10,1.1

Handling Special Values

• If delta is NaN for a Pareto solution (no matches found), it should not be included in final results (it would be filtered out during F1 > 0.5 check or during Pareto detection)
• All reported solutions should have valid (non-NaN) F1 and delta values
