Description

Changes a setting in the COSX JK algorithm to a more conservative default.

Previously, the incremental fock option (cosx_incfock) was enabled by default. This gave a minor speedup, but it came at the risk of possible SCF convergence issues when using diffuse basis sets. This PR disables this option, so the COSX algorithm will be slightly slower, but more robust by default.

Todos

  • Changed cosx_incfock default

  • COSX tests still pass
