Mintardjo asked me whether Imprimis 3 didn't have a core clear, since it did not kill his 'Empty' do-nothing program. Indeed, Imprimis 3 did not have a real core clear. I started thinking about it and decided it would be worth a few tests. Result - Imprimis 4. Not quite up to Sphinx stature, but definitely an inprovement. Basically it is a mod-4 stone which gets most of the early cycles, but kills itself after the mod-4 pattern is complete. There is also an anti-vampire tracer which is converted to a core-clear by the stone (before it dies). The core clear finishes just before it is overrun by the imps, and just before 80,000 cycles elapse. I do not think the resulting imp-gate does much good, looks like gating your own imps is harder than gating your opponent's imps - since you have to interleave the processes - imp/gate/imp/gate/imp/gate... Maybe someone could suggest a launcing sequence that would do that? Also, it is clear in my tests that the long startup is a problem, and Imprimis 4 sometimes gets stunned/vamped before it gets out of the starting block. ;redcode ;name Imprimis 4 ;kill Imprimis ;author P.Kline ;strategy stone like ExtraExtra ;strategy two 3-point spirals like Impression ;strategy anti-vampire code ;strategy core clear -> imp-gate ;strategy sorry - sink wouldn't fit d equ 2667 stone mov <5630,stone+3044+1 extra spl -1,
