v1.3.1

• Improved tangent ( J. Chem. Phys. 113, 9978–9985 (2000) ) for NEB method (-bneb)
• Implementation of NEB method using Hessian (-fc, nebmain.py)
• Fixing minor bugs
• Refactoring

v1.3

• Improved program for NEB method (nebmain.py)
• Implementation of image dependent pair potential method to generate initial path (-idpp)
• Option to adjust the distance between images (-ad)

v1.2

• Fix typos and bugs
• Add new functions (optimization.py, relaxed_scan.py, conformation_search.py)

v1.1

• fix bugs
• improvement of calculation speed for bias potential (-rp, -rpv2, -kpv2, -kav2, -kdav2, etc.)
• Modified method of generating model Hesse matrices (improved performance of structural optimization for >100 atoms) (approx_hessian.py)

v1.0.1

Fix a small bug

v1.0-stable

I will officially release this code as a stable version.
This program is an optimizer to apply artificial potentials that cannot be achieved with the basic features of various quantum chemical simulation software (Gaussian Turbomole, etc.). You can mainly use this software to create an initial structure to calculate the transition state structure.
