Fides 0.3.2

• Change x convergence criteria

Fides 0.3.1

• Fix convergence checks and stop optimization when tr radius becomes too small
• Change default switch iteration for Hybrid Hessian Approximaiton
• Check for degeneracy in SR1 updates

Fides 0.3.0

• Adds new Hybrid Updating Scheme that generates an approximation from the start, but only applies is after a certain number of iterations.

Fides 0.2.5

• Changes default tolerances for FATOL and FRTOL
• Fixes 2D subspace computation, this previously led to inaccurate results for parameters close to the boundary.
• Fixes the trust region radius updating scheme, previously internal solutions to the trust region subproblem would force radius decrease.

Fides 0.2.4

• Changes acceptance criteria to accept steps independently of trust region refinement

Fides 0.2.3

• Improve 2D subspace performance for ill-conditioned problems

Fides 0.2.2

• Refactored code organization
• Improved Hessian Update initialization
• Refactored and improved logging
• Fixed bugs for empty subspaces and singular hessians

Fides 0.2.1

• Updates default algorithms after evaluation on benchmarks
• Adds single_reflect strategy
• Some minor updates to logging

Fides 0.2.0

• Fixes another bug for 0-dimensional subspaces
• Makes mixed truncation/reflection default option
• Adds option to refine steps via trust-constr optimization (enabled by default)
• Removes convergence based on too small delta
• Adds several dimension checks that should better safeguard against malformed user input.

Fides 0.1.1b

• Fixed a bug to handle empty subspaces more graciously
• No longer require setting of dimensionality when initializing HessianApproximation
• Add a couple more dimensionality checks
