chapter3 optimization

decision variable, solution(solver of spreadsheet), optimum point, constraint, objective function, optimization problem, profit, feasible area, executable, linear programming, assumption and correlation are technical term for me.

Finally profit is maximum to solve a optimization problem.

1 using objective function we realize object

* object is for maximum or minimum.
* for example c1x1 + c2x2 = P
* c is constraint, x is decision variable and P is object

2 display some constraints in a graph

* able to choice only in feasible area
* often feasible area transform by new constraint

3 using solver of spreadsheet and we received optimization

* enter objective function to target cell, decision variable to blank cell, add constraints and execute

4 correct assumption to fit object of the analysis

5 using following, again to optimize

* consider correlation of ducks and fish
* result is following
