/-----------------------------\ | Xine - issue #3 - Phile 113 | \-----------------------------/ Introduction to the Conway cellular life automata By [Star0/ikx] All of us know robots , how they work ? eh , large question ,they use bits and electric impulses in their circuits , so they have reactions in some cases when some bits are combined , some part of the bot analyse them and then give reactions ( light , laser , boum boum , sound , etc etc ) A lot of people want to create something like life with robots . In fact , it's an human dream , but like all human dreams , they aren't 100% impossible . Human robots are pretty difficult to realise , but cellular life appears easyer . To define an automate,an automate gives always logic reaction to an event This goes again Chaos Theory that appears a lot in evolution and mutation, when you see a dog , you ask yourself why he goes there and why there , he can also go there and there. So, imagine the Automate 1, when you give him 1 he reply 0, when you give him 0 , he reply 1 In some word : 0 -컴> 1 1 -컴> 0 You already seen than I haven't choosed the difficulty in this article. Now , not really more difficult , imagine the infinite divided by squares. In some word, a big chessboard. Each square can have two states, dead or alive 旼컴코컴컴旼컴코컴컴� Now we define the automate , simply , � � 栢 � � 栢 � <컴�-- Alive there are two rules 쳐컴컬컴컴쳐컴컬컴컴� � 栢 � � 栢 � � <� 1� if a square has three other quad 쳐컴컬컴컴쳐컴컬컴컴� � alive near it then this case goes � � 栢 � � 栢 � 읕�-- Dead alive at next generation 읕컴컥컴컴읕컴컥컴컴� 2� All case alive die at next 旼컴코컴컴旼컴커 旼컴코컴컴旼컴커 generation , there's two exceptions , � 栢 � 栢 � � -> � 栢 � � 栢 � in case of first rules and if the 쳐컴컬컴컴쳐컴캑 쳐컴컬컴컴쳐컴캑 square has two squares alive near it � 栢 � 栢 � 栢 � � � � � 쳐컴컬컴컴쳐컴캑 쳐컴컬컴컴쳐컴캑 With this two rules appears two � 栢 � 栢 � 栢 � -> � 栢 � � 栢 � concepts of the life , first and the 읕컴컥컴컴읕컴켸 읕컴컥컴컴읕컴켸 more important,reproduction , second , with life appaers movement Some scheme to which are applied the two principes : 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� 旼컴코컴컴旼컴코컴컴� 旼컴코컴컴旼컴코컴컴� � � � � � � � � � � In this case, the colony 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� stay stable and doesn't � � 栢 � 栢 � � -컴컴> � � 栢 � 栢 � � move without any events 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� � � 栢 � 栢 � � -컴컴> � � 栢 � 栢 � � There's no movement here 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� � � � � � � � � � � 읕컴컥컴컴읕컴컥컴컴� 읕컴컥컴컴읕컴컥컴컴� 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� 旼컴코컴컴旼컴코컴컴� 旼컴코컴컴旼컴코컴컴� 旼컴코컴컴旼컴코컴컴� � 栢 � � � � � � � � � � � � � � 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� � � 栢 � � � -컴�> � � 栢 � � � -컴�> � � � � 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬 Dead! 컬컴컴� � � � 栢 � � -컴�> � � � 栢 � � -컴�> � � � � 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� 쳐컴컬컴컴쳐컴컬컴컴� � � � � 栢 � � � � � � � � � � � 읕컴컥컴컴읕컴컥컴컴� 읕컴컥컴컴읕컴컥컴컴� 읕컴컥컴컴읕컴컥컴컴� Here the colony goes to the death , it kill himself why? because it is too small to survive , this is also something that approach form the theory of evolution 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� 旼컴코컴컴旼컴코컴컴旼컴코 旼컴코컴컴旼컴코컴컴旼컴코 � � � � � � � � � � � � 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 � � � � � � -컴> � � � 栢 � � � 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 � � 栢 � 栢 � 栢 � � � � � 栢 � � � 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 � � � � � � <�-- � � � 栢 � � � 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 � � � � � � � � � � � � 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 쳐컴컬컴컴쳐컴컬컴컴쳐컴컬 The colony stay stable , but there's a movement from step 1 to step 2 , and from step 2 to step 1 , a boucle appaers 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� this system is pretty simple isn't ? yeah , but when complex colony appears with 100 ( or 200 millions ) of life appears , reaction are more complex , there's interesting colony who born , they have the particularity to create another colony ( life fish ) , I have intented to code this concept in asm ( I'm crazy I know ), the best thing of this game is that this concept help many scientists to resolve math problems , don't ask me how Les petits d굃inquants (C) Star0 '98
