### 8. PIECEWISE LINEARIZATION

2011-4-2 · 95 This is an LP problem because each new fi is linear and each fi ≈ f(X) over some range of X. The LP solution will be u = f2(X) because it is less than f1 or f3 and therefore closer to f(X) when 3 ≤ X ≤ 10. So the max value of u = a2 b2 (5). Note that in the range 0 ≤ X ≤ 3 f1 is the smallest and for X ≥ 10 f3 is smallest. Similarly we could minimize a convex function
