Acknowledgement
First and foremost, I would like to thank God that finally, I have succeeded in
finishing this project work. I would like to thank my beloved Additional Mathematical
teacher, Mr. ee ian !i for all the guidance he had provided me during the process in
finishing this project work. I also appreciate his patience in guiding me completing this
project work. I would like to give a thousand thanks to my father and mother for giving
me their full support in this project work financially and mentally. hey give me moral
support when I needed it. I would also like to give my thanks to my fellow friends who
had helped me in finding the information that I am clueless of, and the time we spent
together in study groups on finishing this project work. "ast but not least, I would like to
e#press my highest gratitude to all those who give me the possibility to complete this
coursework. I really appreciate all the help I got. Again, thank you very much.

Global Ma#imum/Minimum
In mathematical analysis,the ma#ima and minima (the plural of ma#imum and
minimum$ of a function, known collectively as e#trema (the plural of e#tremum$, are the
largest and smallest value of the function, either within a given range (the
local or relative e#trema$ or on the entire domain of a function (the global or
absolute e#trema$. 0ierre de Fermatwas one of the first mathematicians to propose a
general techni1ue, ade1uality, for finding the ma#ima and minima of functions.
As defined in set theory, the ma#imum and minimum of a setare the greatest and least
elementsin the set, respectively. 2nbounded infinite sets, such as the set of real numbers,
have no minimum or ma#imum.

Method to achieve the best outcome (such as ma#imum profit or lower cost$ in a
mathematical model whose re1uirements are represented by linear relationships.It is a special case of mathematical programming.
A techni1ue for the optimi'ation of a linear objective function, subject to linear
e1uality and linear ine1uality constraints. @an be applied to various field of study. It is used in business and economies, but
can also be utili'ed for some engineering problems. Industries that us linear
programming models include transportation, energy, telecommunication, and
manufacturing. It has proved useful in diverse type of problems in planning,
routing, scheduling, assignment and design. Many practical problems in operations research can be e#presses as linear
programming problems. @ertain special cases of linear programming, such as
network flow problems and multicommodity flow problems are considered
important enough to have generated much research on speciali'ed algorithms for
their solution. Listorically, ideas from linear programming have inspired many of
the central concept of optimi'ation theory, such as duality, decomposition and the
importance of conve#ity and its generali'ations.
