SimpleTuringMachine

This is a simple Turing-Machine implemented in C/C++. Its a simple singletape design so you can run simple programs. Each step will be printed in the console. The programming synta is easy and you can define further settings like:

• Tapesize
• Start-Rule
• End-Rule
• Tape default state
• Tape startup state
• Head start position

SYNTAX

• tape_size,_SIZE_
• start_rule,_RULE_ID_
• tape_conf,_STATE_TO_SET,_POS_1_(,_POS_2_,...)\n

A rule is a set of IF STATE THEN WRITE statements = rule_set_entry Every rule_set_entry with the same id belongs to a ruleset. So for example :

• IF HEAD READS 0 -> WRITE 1 ((optional) MOVE HEAD)
• IF HEAD READS 1 -> WRITE 2 ((optional) MOVE HEAD) For this example, the rule_set has 2 entries.

These will look like this:

• rule_set,0,0,1,0,0
• rule_set,0,1,0,0,0

with head movement (move +1):

• rule_set,0,0,1,0,1
• rule_set,0,1,0,0,1

So the general syntax of a rule_set_entry look like this:

• `rule_set,RULE_ID,IF_STATE,WRITE_THAT,MOVE_HEAD(-1,0,+1),NEXT_RULE

SAMPLE PROGRAM - ADD ONE TO A BIN-NUMBER

const char* turing_add_one_program = "tape_size,32\n"
"start_head_pos,3\n"
"start_rule,0\n"
"tape_conf,1,1,2,3\n" //zelle 1,2,3 auf 1 setzten//RULESET 1 df
"rule_set,0,0,1,-1,1,1\n" //<- START RULE
"rule_set,0,1,0,-1,0,0\n"
"rule_set,0,-1,1,0,2,-1\n"//RULESET 2
"rule_set,1,0,0,-1,0,1\n"
"rule_set,1,1,1,-1,0,1\n"
"rule_set,1,-1,-1,1,2,0\n";//eig kommt noch ein zweites aber durch die 2 wird direkt abgebrochen
