What is Vagueness
It is widely accepted that a term is vague to the extentthat it has borderline casesWhat is a borderline caseA case in which it seems possible either to apply or notto apply a vague termThe adjective ldquotallrdquo is a typical example of a vaguetermExamples
Serena is 175m tall is she tallIs Betelgeuse a huge starIf you cut one head off of a two headed man have youdecapitated himEubulides of Miletus The Sorites ParadoxThe old puzzle about bald people

Defining Vagueness
Bertrand Russell Per contra a representation isvague when the relation of the representingsystem to the represented system is notone-one but one-manyExample A small-scale map is usually vaguer than alarge-scale mapCharles Sanders Peirce A proposition is vaguewhen there are possible states of thingsconcerning which it is intrinsically uncertainwhether had they been contemplated by thespeaker he would have regarded them asexcluded or allowed by the proposition Byintrinsically uncertain we mean not uncertain inconsequence of any ignorance of the interpreterbut because the speakerrsquos habits of languagewere indeterminateMax Black demonstrated this definition using the wordchair

What is Vagueness
It is widely accepted that a term is vague to the extentthat it has borderline casesWhat is a borderline caseA case in which it seems possible either to apply or notto apply a vague termThe adjective ldquotallrdquo is a typical example of a vaguetermExamples

What is Vagueness
It is widely accepted that a term is vague to the extentthat it has borderline casesWhat is a borderline caseA case in which it seems possible either to apply or notto apply a vague termThe adjective ldquotallrdquo is a typical example of a vaguetermExamples

Defining Vagueness
Bertrand Russell Per contra a representation isvague when the relation of the representingsystem to the represented system is notone-one but one-manyExample A small-scale map is usually vaguer than alarge-scale mapCharles Sanders Peirce A proposition is vaguewhen there are possible states of thingsconcerning which it is intrinsically uncertainwhether had they been contemplated by thespeaker he would have regarded them asexcluded or allowed by the proposition Byintrinsically uncertain we mean not uncertain inconsequence of any ignorance of the interpreterbut because the speakerrsquos habits of languagewere indeterminateMax Black demonstrated this definition using the wordchair

Defining Vagueness
Bertrand Russell Per contra a representation isvague when the relation of the representingsystem to the represented system is notone-one but one-manyExample A small-scale map is usually vaguer than alarge-scale map
Charles Sanders Peirce A proposition is vaguewhen there are possible states of thingsconcerning which it is intrinsically uncertainwhether had they been contemplated by thespeaker he would have regarded them asexcluded or allowed by the proposition Byintrinsically uncertain we mean not uncertain inconsequence of any ignorance of the interpreterbut because the speakerrsquos habits of languagewere indeterminateMax Black demonstrated this definition using the wordchair

Aristotle in Περὶ ἑρμηνεῖας (De Interpretatione)discussed the problem of future contingencies (iewhat is the truth value of a proposition about a futureevent)Can someone tell us what is the truth value of theproposition ldquoAt Christmas there will be snow in AthensGreecerdquoJan Łukasiewicz defined a three-valued logic to dealwith future contingenciesEmil Leon Post introduced the formulation of 119899 truthvalues where 119899 ge 2CC Chang proposed MV-algebras that is an algebraicmodel of many-valued logicsIn 1965 Lotfi A Zadeh introduced his fuzzy settheory and its accompanying fuzzy logic

Physical Interpratation 119880 set of programs that generate bitstream and elements of 119883 are assertions aboutbit streams
Example If 119906 generates the bit stream 010101010101hellipand ldquostarts 01010rdquo isin 119883 then119909 ⊧ starts 01010
Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Bertrand Russell Per contra a representation isvague when the relation of the representingsystem to the represented system is notone-one but one-manyExample A small-scale map is usually vaguer than alarge-scale mapCharles Sanders Peirce A proposition is vaguewhen there are possible states of thingsconcerning which it is intrinsically uncertainwhether had they been contemplated by thespeaker he would have regarded them asexcluded or allowed by the proposition Byintrinsically uncertain we mean not uncertain inconsequence of any ignorance of the interpreterbut because the speakerrsquos habits of languagewere indeterminateMax Black demonstrated this definition using the wordchair

Physical Interpratation 119880 set of programs that generate bitstream and elements of 119883 are assertions aboutbit streams
Example If 119906 generates the bit stream 010101010101hellipand ldquostarts 01010rdquo isin 119883 then119909 ⊧ starts 01010
Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Physical Interpratation 119880 set of programs that generate bitstream and elements of 119883 are assertions aboutbit streams
Example If 119906 generates the bit stream 010101010101hellipand ldquostarts 01010rdquo isin 119883 then119909 ⊧ starts 01010
Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Physical Interpratation 119880 set of programs that generate bitstream and elements of 119883 are assertions aboutbit streams
Example If 119906 generates the bit stream 010101010101hellipand ldquostarts 01010rdquo isin 119883 then119909 ⊧ starts 01010
Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment

Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Letrsquos be practical
Physical Interpratation 119880 set of programs that generate bitstream and elements of 119883 are assertions aboutbit streams
Example If 119906 generates the bit stream 010101010101hellipand ldquostarts 01010rdquo isin 119883 then119909 ⊧ starts 01010
Fuzzy Bit Streams Assume that 119909prime is a program thatproduces bit streams like the following
0 1 0 1 0 1 0 1 0
Explanation The bits above are distorted because of someinteraction with the environment
Result 119909prime satisfies the assertion ldquostarts 01010rdquo tosome degree

Bart Kosko has argued that fuzziness ldquomeasures thedegree to which an event occurs not whether it occursRandomness describes the uncertainty of eventoccurrencerdquoAccording to this thesis expression 120572(119906 119909) would denotethe degree to which program 119906 will output a bitstreamthat will satisfy assertion 119909When 120572(119906 119909) = 0 119906 will not generate a bitstream thatsatisfies 119909When 120572(119906 119909) = 1 119906 will definitely generate a bistreamthat satisfies 119909This new physical interpretation is based on theassumption that the programs behave dynamically andnondeterministic
