• Complexity - 1.84.0 (https://www.boost.org/doc/libs/1_84_0/libs/icl/doc/html/boost_icl/implementation/complexity.html )
  In "Table 1.15. Time Complexity of Addition", interval set/separate interval set/split interval set/interval map/split interval map += interval_sets/interval_maps 's time complexity is O(m log(n+m)), but this time complexity should be at least interval set/separate interval set/split interval set/interval map/split interval map += T::segment_type 's time complexity (O(n)). Example: the interval_sets/interval_maps contains only one big interval (whose type is T::segment_type), and this interval makes interval set/separate interval set/split interval set/interval map/split interval map += T::segment_type 's time complexity O(n).

• Addition - 1.84.0 (https://www.boost.org/doc/libs/1_84_0/libs/icl/doc/html/boost_icl/function_reference/addition.html )
  In "Table 1.23. Time Complexity for inplace Addition on interval containers", interval_set/separate_interval_set += interval_sets, split_interval_set += interval_sets and interval_maps += interval_maps have wrong time complexity.

• Subtraction - 1.84.0 (https://www.boost.org/doc/libs/1_84_0/libs/icl/doc/html/boost_icl/function_reference/subtraction.html )
  In "Table 1.26. Time Complexity for inplace Subtraction on interval containers", interval_sets -= interval sets and interval_maps -= interval sets/interval maps have wrong time complexity.

• Insertion - 1.84.0 (https://www.boost.org/doc/libs/1_84_0/libs/icl/doc/html/boost_icl/function_reference/insertion.html )
  In "Table 1.29. Time Complexity for inplace insertion on interval containers", insert(interval_set/separate_interval_set, interval sets), insert(split_interval_set, interval sets) and insert(interval_maps, interval maps) have wrong time complexity..

• Intersection - 1.84.0 (https://www.boost.org/doc/libs/1_84_0/libs/icl/doc/html/boost_icl/function_reference/intersection.html )
  In "Table 1.36. Time Complexity for inplace intersection on interval containers", interval_sets &= interval sets and interval_maps &= interval sets/interval maps have wrong time complexity.

• Symmetric Difference - 1.84.0 (https://www.boost.org/doc/libs/1_84_0/libs/icl/doc/html/boost_icl/function_reference/symmetric_difference.html )
  In "Table 1.39. Time Complexity for inplace symmetric difference on interval containers", interval_sets ^= interval sets and interval_maps ^= interval sets/interval maps have wrong time complexity.
