## プロジェクトの歴史と使われ方

IBEX is a C++ numerical library for interval arithmetic and constraint programming over real numbers, distributed with command-line tools such as IbexSolve and IbexOpt.

### プロジェクトの歴史

The IBEX documentation describes the library as a layered toolkit: symbolic-numeric interval calculations, contractor programming, and system solving or global optimization. The documentation copyright line spans 2007-2020 under IMT Atlantique, while the GitHub repository records release tags from the 1.x series through the 2.x series.

### 採用の歴史

IBEX is a specialist scientific-computing package rather than a mass-market developer tool. Its adoption is visible through the maintained documentation site, GitHub releases, Homebrew packaging, and the presence of solver executables that let users try interval methods without embedding the C++ API first.

### 使われ方

Users apply IBEX to constraint satisfaction, set characterization, interval computations, contractor-based pruning, and global optimization. The docs emphasize reliable characterization with boxes and account for uncertainty sources such as floating-point approximation, round-off error, model uncertainty, and measurement noise.

### パッケージ好きにとっての重要性

IBEX matters to package nerds because it is a rare Homebrew formula in the rigorous numerical-constraint niche: it packages both a C++ library and solver CLIs, pulls in parser/build dependencies such as Bison, Flex, CMake, and pkgconf, and exposes a domain-specific modeling language, Minibex.

### タイムライン

- 2007-2020: The published documentation carries an IMT Atlantique copyright range.
- ibex-1.19: The repository contains a release tag for the 1.x line.
- ibex-2.0.x: The repository tag history shows the transition to the 2.x line.
- 2025: The GitHub releases page lists v2.9.1 as an April 2025 release.

### Related projects

- The documentation says IBEX relies on third-party interval arithmetic libraries such as Gaol or Filib depending on platform, and it points to plugins or packages for affine arithmetic, AMPL compatibility, and semi-infinite programming.
