Grading: is it meaningful?
How can the entire class get an A?
The story of Lightning.

Get information from history.
How would you repair the situation?

I play a double role:
As user of the software you create and as your professor.
As your professor I want to know whatever you want to share with me.
With the users of your software and your paying customers
the story is different. Be careful with ponting fingers at users.

Subproject 3

===========================================
Review of concepts of SCG game
Needed for Requirements Analysis

Roles:
Component Market Administrator
Collects reusable components

T Ball:
challenge d
break-even[d]
look-ahead[d](b)
look-ahead[r](b)

maximize look-ahead polynomial
maximum bias: b_max

break-even[d] = look-ahead[d] (b_max)

break-even[d] if problems may be arbitrary large



Code review

SCG moving beyond TBall:
Two relations: solve multiple problems similar to one relation.
R1, R2
r a problem using R1 and R2.

look-ahead[r(t1,t2)](b) = t1*look-ahead[R1](b) + t2*look-ahead[R2](b)
t1 + t2 = 1
Find minimum t1 by trying 100 values?

2 and 6: ?



Requirements analysis for problem construction
Making challenges attractive.

  - symmetric, but how big should n be?

  - generating all combinations: bin(n,k) = bin(n-1,k) + bin (n-1,k-1)
    bin(4,2) = bin(3,2) + bin(3,1)
