Help with WinLifeSearch

Postby Sokwe » October 5th, 2009, 10:00 pm

I am trying to find a c/4 orthogonal domino sparker that is restricted as in the state attached below (it can be any length or width, but cannot cross the lines of off cells). My question really is, how would one set this up further so as to reduce the search to a reasonable length of time? Also, how long would such a search take? I have been performing various tests over the past few days but have not been able to come up with a working result.

Might it be a good idea to use the back of this spaceship when setting it up?
x = 31, y = 11, rule = B3/S23
13bo$12b4ob3o$10bo2bobo$5b2o3b3ob4o2bo$4bo2bo7bo3b2o9bo$b2ob2o4bobobob

2o11b2o!


It would be nice if some of the people that are more familiar with WLS would try to explain how to use the program effectively.

Wouldn't that be OK for your purpose?

x = 32, y = 13, rule = B3/S23

o$13b2o!


There is also my blinker puffer as a start:
x = 40, y = 39, rule = B3/S23

Nicolay found several variants. I propose that you check the archives of the life list.

In general: When searching a ship with a specific spark using WLS you need to restrict the searcg space to find a result in resonable time. Usually the best idea is to first concentrate on the core area and afterwards search for supporting arms until you find something familiar. Or try to combine something familiar that does half of the job and combing that with something to search. You need normally a lot of patience and/or experience to recognize familiar parts.

It helps to search for a combination of short wide supporting parts and long narrow parts.

There is an article by David Bell (Archives of the lifelist) explaining how to complete c/3 puffer engines. This might help as well.

Simply setting up a general search and just waiting won't give you a result in reasonable time. This is just a valid option when searching for very general things, e.g. a c/7 space ship.

Well, I'm trying to search for a 2c/9 spaceship, with WLS.

In Search settings(Options - Search Settings Or F6 key), Which preset is most efficiency?
