C++ Standard Template Library Algorithms for Quantitative Finance

Summary

This overview surveys pre-C++11 Standard Template Library algorithms that operate on ranges through iterators. It groups them by purpose: inspecting elements, transforming or copying values, removing duplicates or matching values, reordering ranges, sorting, searching sorted data, and performing numeric operations. Examples include counting and searching, copying and replacing, partitioning, sorting and heap operations, binary search and set operations, plus accumulation and partial sums. It emphasizes that these tools can reduce the need to write common routines from scratch in quantitative finance code.

The article also notes an important distinction: many algorithms change element values or order without resizing the underlying container. Removal algorithms, for example, reorganize a range but do not themselves change its container size. The material is a reference-style catalog rather than a benchmark or finance-specific application. Its guidance is limited to the pre-C++11 library; it points readers toward later coverage for newer algorithms and relies on external reference material for performance guarantees.

Key ideas

• STL algorithms apply operations to ranges through iterators and are grouped by their behavior and use.
• Many modifying algorithms alter values or ordering without changing the container’s size.
• Sorting and sorted-range algorithms can support efficient ordering, searching, and set operations.
• Numeric algorithms combine or transform sequences, including sums, inner products, differences, and partial sums.
• The catalog covers pre-C++11 algorithms and provides no finance-specific benchmark or case study.
