title: 'arcopt: Adaptive Regularization using Cubics for Optimization'
version: 0.3.0
identifiers:
- type: doi
  value: 10.32614/CRAN.package.arcopt
abstract: Implements cubic regularization methods (ARC) for local optimization problems
  common in statistics and applied research. Provides robust handling of ill-conditioned,
  nonconvex, and indefinite Hessian problems with automatic saddle point escape. Supports
  box constraints; linear equality constraints are planned for a future release.
