Systematic design concept/method

Abstraction Phase

State Transition Diagram

• Combination of Noughts-and-Crosses
  • 362,880(=9!)[patterns] (sum up all patterns)
  • 255,168 (As a game)
  • 26,830 (Eliminating symmetrical pairs)

We added the following rules to reduce the number of transition functions and inputs.

1st 

SYANAC goes to the center of the board. (sq#5)

2nd

Human goes to the specific corner(sq#1) or the edge(sq#4) of the board.

3rd

SYANAC must choose sq#3

Therefore, SYANAC's conbination patterns and inputs are as follows:

• SYANAC
  • 25 combination patterns(Eliminating symmetrical pairs)
  • 7 types of inputs

The State Transition Diagram shown right describes SYANAC's behavior based on this rule.

State Transition Diagram Demonstration

if we test all of the SYANAC's move, we can draw this STATE TRANSITION DIAGRAM for SYANAC.

Logic Gates

When we examined ALL of the patterns in the State Transition Diagram, we can decide logic gates we need in each square.

Here we show you the logic gates of each sq# according to the state transition.

Block Diagram (System/Device)

• System

We determine each square as a system. (So we have to make 9 systems to make SYANAC.) We show some examples in figures below.

• Device

When we look at the Logic Gates of all 9 systems, they are all consisted of YES, AND, AND-AND Gates.

So, what we have to do is to construct these Logic Gates in a simple, systematic way.

Construction Phase

Up/Mid/Downstream

In order to implement logic gates, combination of several kinds of regulator binding sites is necessary. For this reason, separated three regions named upstream, midstream, and downstream as shown in figure is added new prefixes and suffixes in each end.

working model

Here we show you some typical working model examples of the Logic Gates.

• AND Gate (Repressor+Repressor)

• AND Gate (Activator+Repressor)

AND-AND Gates are also able to construct in the same way.

DNA Construction Procedure

• Midstream Parts Insertion

[http://131.112.128.86/downloads/tokyo_mid_insertion.mov Midstream Parts Insertion Procedure (.mov)] (Requires QuickTime)

• Up/Downstream Parts Insertion

Next parts can be inserted with the same procedure. (Up/Downstream Insertion Parts)
