Hi Clement. Good of you to use the '|' but it should actually be on the following term:

(6=58)r2c35 - (5|8=9)r2c8

Also, since you're using a net (which you properly mention), it would be better to show it more clearly in your chain too. In this case a normal memory chain would do. Without any other modifications, I'd write it like this (2r2c9 being the memory candidate):

(9=2*)r2c9 - (2=6)r7c9 - r7c56 = r8c5 - (6|*2=58)r2c35 - (5|8|*2=9)r2c8

...which could be shortened to this:

(9=2*)r2c9 - (2=6)r7c9 - r7c56 = r8c5 - (6|*2=589)r2c358

...and then this (to avoid any explicit netting):

(9=2)r2c9 - (2=6)r7c9 - r7c56 = r8c5 - (6=2589)r2c3589

(which is practically the same as my first solution).

Hi Steve! Seems to me that there's a slight problem with your chain as written. The red-colored 8 has no weak link to the previous node so I guess it's using an implicit memory. I think it would be clearer to make it explicit, but it's kind of hard with the nodes you've chosen. How about something like:

(8)r12c8 = (8*-6)r8c8 = r8c5 - (6=2589)r2c3589 - (*8|9=5)r1c8 ... ?

...or a bit shorter using my comma-style:

(8)r12c8 = (8*,6)r8c85 - (6=2589)r2c3589 - (*8|9=5)r1c8 ...

Thanks, SpAce. That one is hardly worth saving, but I guess the best way is to just run it backwards:

(8=357)r8c127 - (5|7=1)r7c3 - (1=5789)r1c3468 - (9=2568)r2c3589 - 6r8c5 = r8c8 - (6=2589)r1246c8 => -8 r3c7

Hmm. That doesn't make sense. If it runs one way, then it should the other. So looking at my original:

(8=2569)r1246c8 - 6r8c8 = r8c5 - (6=2589) - (8|9=5)r1c8 - (5=178)r1c346 - (1=357)b7p345 - (3=8)r8c7 => -8 r3c7 ; stte

Let's just fix it like this:

(8=2569)r1246c8 - 6r8c8 = r8c5 - (6=2589) - (9=1578)r1c3468 - (1=357)b7p345 - (3=8)r8c7 => -8 r3c7 ; stte

I wouldn't say so. Conciseness and elegance are nice, but they're not necessarily the most interesting solutions.

Let's just fix it like this:

(8=2569)r1246c8 - 6r8c8 = r8c5 - (6=2589) - (9=1578)r1c3468 - (1=357)b7p345 - (3=8)r8c7 => -8 r3c7 ; stte

Yep, that's a perfect fix!
