What is if a then b condition? It's not a straightforward conditional like <code>if a then: b; else:a;</code>. Looks more like if we define false < true, and "maybe" means "unknown state of either true or false", the "if a then b" condition is the same as a <= b. Some clarification? --[[User:Ledrug|Ledrug]] 01:07, 27 August 2011 (UTC)

test case

re: "Kudos (κῦδος) for actually thinking up a test case algorithm where ternary logic is intrinsically useful, optimises the test case algorithm and is preferable to binary logic".

I know that calculating Perfect numbers and Matrix-exponentiation_operator in binary has some algorithmic advantages. I imagine that there is some problem would benefit from Ternary logic. Any hints or suggestions?

On first reading, it seems like you are implementing an analogue of the cmp function from C and C based languages. Or am I completely misunderstanding? --Thundergnat 11:03, 26 August 2011 (UTC)

Task structure

How about adding a truth table for implementation and cutting the history/leaving a link to the history?--Paddy3118 08:29, 26 August 2011 (UTC)

Just added the Logic Operators in Truth Tables. NevilleDNZ 11:33, 26 August 2011 (UTC)

C example

Could have been better (I could have bothered to do a table), but I hope the C example is sufficiently and approriately clear, fast and clever. Hopefully, I'll get around to implementing the C++ version using templates. --Michael Mol 17:23, 26 August 2011 (UTC)

if a then b

What is if a then b condition? It's not a straightforward conditional like if a then: b; else:a;. Looks more like if we define false < true, and "maybe" means "unknown state of either true or false", the "if a then b" condition is the same as a <= b. Some clarification? --Ledrug 01:07, 27 August 2011 (UTC)

if a then b is logically equivalent to (not a) or b. --Kernigh 01:27, 27 August 2011 (UTC)
