The improved gauge action with rectangle term:
![\[ S_G=-\frac{\beta}{N_c}\left(c_0\sum_p{\rm Re}{\rm Tr} U_p +c_1\sum_r{\rm Re}{\rm Tr} U_r\right) \]](form_5.png)
-
one plaquette term is added.
-
Two rectangular terms are added:

x <---+ | |
x v
-
We use Wk, Wk' for the boundary spatial link.
-
Contributions from the boundary spatial plaquettes and rectangles are set to zero.
-
The temporal rectangle that cross the boundary is set to zero.

The force for the rectangle improved gauge action with the SF boundary.
-
We use Wk, Wk' for the boundary spatial link.
-
The boundary improvement factor ct, ctr is implemented.
-
ctr is multiplied to the following temporal rectangle staple
+---+---+ +---+---+

Force for the boundary spatial link is set to zero.

+---+---+ +---+---+
-
We notice that the upper and lower staple accompanied with the boundary spatial link is set to zero by Staples_SF::upper() and Staples_SF::lower(). Corresponding contributions to the boundary spatial link are automaticaly zero.
-
Contribution from the non existing rectangle is automatically zero by Staples_SF::upper() and Staples_SF::lower().
