Best Designs - Linac900Ext7tc2

Does phase really matter? We increased the yield when we extended the time, and re-centered the phase range with Linac900Ext6tc2, but is that sort of improvement possible on the worst of the d2 lattices? Let's see...

The best design was 3.730295% by a Boinc Wrapper user (there is no way to tell who it is)

As with last week, we noticed that a swap of the phase meant that it drastically improved yields. so would the worst of the Ext series to day, Linac900Ext7d2 benefit from that swap too? It wyould appear so.

While it was not as good as last weeks 6tc2 result, it did give a substantial improvement in yield, despite fewer simulations run (although double the MPTS were calculated).

The search space is in the 10258 range with 86 parameters. The lattice showed a single-stage growth pattern.

This is the 'best' design as recreated in v4.45. The original simulation length as recorded was 1 hour, 39 minutes 08 seconds.
