I, SATVIR SINGH, declare that this thesis entitled, INVESTIGATIONS IN EVOLUTION OF TYPE-1 AND TYPE-2 FUZZY SYSTEMS and the work presented in it are my own. I confirm that:

\begin{itemize}
\item[\tiny{$\blacksquare$}] This work was done wholly or mainly while in candidature for the research degree at this University.
\item[\tiny{$\blacksquare$}] Wherever I have consulted the published work of others, this is always clearly attributed.
\item[\tiny{$\blacksquare$}] Wherever I have quoted from the work of others, the source is always given. With the exception of such quotations, this thesis is entirely my own work.
\item[\tiny{$\blacksquare$}] I have acknowledged all main sources of help.
\item[\tiny{$\blacksquare$}] Wherever the thesis is based on work done by myself jointly with others, I have made clear exactly what was done by others and what I have contributed myself.
\\
\end{itemize}
