After noon class with Computer Intelligence by Pro.Chu part 2

if you have
- 1,000,000
- then u have a b c d = price  = decision variable
- p,q,r,s = amount

then
q <= p/2

in generic form
q- 0.5 p<=0

in function form
F(p,q,r,s) = p*a' +q *b' + r* C' +s *D'

other constraints
1,000,000 -  p*a +q *b + r* C +s *D = 0

what is harder in equality and inequality so the answer is equality

the number of optima = optima = data =พหูพจ
เอกพจ= datum = optimum
unimodal
 one clear optimum
multimodal more than one optima
deceptive false optima

f(x)=sin^4 (5 pi x)


Schwefel's function  the answer is near an edge it's have special algorithm to find (search for more information)



Type of an optimization problem
 ความเสียงคือความไม่แน่นอน
Uniobjective  = one objective
Multiobjective

Optima type
 Global minimum
  The solution x* E F, is a global minimum of f,  if
         f(x*) < f(x) , for all x E F , where F union S

Local search algorithm
  use only info search space surrounding the current solution to produce a new solution
Global search algorithm
  explore the entire search space

exploration การค้นหาบริเวณกว้าง global
exploitation การค้นหาเฉพาะที่ local

Sigma = summation
Big pi = multiplication
