ofind working example?

Post by Scorbie » May 2nd, 2015, 8:45 am

I remember the last time I used ofind (which is quite long ago), it did report some results in small parameters.
But now whatever I feed in, ofind just puts out ....................
Even if I get new source code from the internet, the same thing happens.
Can anyone help me find out what I am doing wrong?
This is one of the many inputs I tried, just in case you're wondering.

Code: Select all

ofind 0.9, D. Eppstein, 14 August 2000
Type ? at any prompt for help, or ^ to return to a previous prompt.
Rule: b3/s23
Period: 2
Symmetry type (even, odd, none): even
Allow symmetric completion of patterns (yes, no): yes
Rotor width: 2
Stator width: 3
Allow final stator rows to exceed width limit (yes, no): yes
Maximum deepening amount: 2
Number of initially specified rows: 0
Initializing... Searching...

Okay, Now I know the problem occurs when one compiles the code in 64bit executable. Not sure exactly why.

Bug in ofind?

Post by Scorbie » December 27th, 2015, 11:36 pm

Is it just my computer or can anyone reproduce this bug?

Code: Select all

ofind 0.9, D. Eppstein, 14 August 2000
Type ? at any prompt for help, or ^ to return to a previous prompt.
Rule: b3s23
Period: 4
Symmetry type (even, odd, none): even
Allow symmetric completion of patterns (yes, no): yes
Rotor width: 6
Stator width: 5
Allow final stator rows to exceed width limit (yes, no): yes
Maximum deepening amount: 0
Number of initially specified rows: 1
Specify initial phase of each row; '.'=dead, 'o'=live.
...o
.
.
.
Returns this:

Code: Select all

x = 20, y = 14, rule = B3/S23
6bo6bo$6bo6bo$5b3o4b3o3$3b2obo6bob2o$b3ob3o4b3ob3o$o4bob6obo4bo$b3obo

Which unfortunately breaks in Life.

I get the same result - same version of ofind built on Win7 with Visual Studio.
Without 'Allow symmetric completion of patterns' a working oscillator is returned.
The 5S project (Smallest Spaceships Supporting Specific Speeds) is now maintained by AforAmpere. The latest collection is hosted on GitHub and contains well over 1,000,000 spaceships.
