Best Designs - Linac900Ext6X

A new lattice, and another modification. Would the new client handle the RF phases better than the older client? Would the finer control of the phases make a difference? Only one way to find out.

The best design was 3.440846% by a Boinc Wrapper user (there is no way to tell who it is)


AThe release of this lattice (and next wee's 10tc2 lattice takes us right back to the beginning in some ways. This lattice came out just days before this 'best design' project was started, a little over 9 months ago.

The aim, as described at the time, was to try and avoid local maximums in 6Xc2 by resetting the RF phase back to it's finer grained, single-loop. This should lead to different design paths and perhaps, a better design.

The search space is in the 10¹⁹⁸ range with 66 parameters. The lattice showed a single-stage growth pattern.

The X in the lattice name, replaces the t and also indicates extended time, but also marked it as lattice that required v4.45 at minimum.

This is the 'best' design as recreated in v4.45. The original simulation length as recorded was 57 minutes 05 seconds.
