Hello,

Problem Paradise issue 20 just appeared after a long delay 
with three retro originals in it.  

The editors has changed :

Send solutions to the chief editor Tadashi Wakashima at 
tadashi at wombat.zaq.ne.jp

Send originals to me, the retro editor Satoshi Hashimoto at

I have only one original(#4 with a light retro motivation) 
now.  Your contribution will be highly appreciated.
