b. TCE CCSD(T)

The input file that follows (generated with ./make_nwchem_input.py w7 ccsd-t cc-pvtz energy) is the one that must be used. The only lines that you can change are noted as such.

This input should produce the same answers as 1a but uses a completely different implementation, with different algorithms.
