from math import sqrt

# Find an approximate solution to the weighted set packing problem using
# Halldorsson's algorithm (2000). Our approximate solution is at worst only a
# factor of sqrt(m) worse than the optimal solution.
#
# Input:
#     S = { a, b, c... }            # Set of base elements (m = |S|)
#     C = { C_1, C_2, C_3, ... }    # Collection of weighted subsets of S
#     C_i = ({ a, c, ... }, weight) # Weighted subset of S
