f(x) = 12.096x₁ + 21.504x₂ – 1.732x₁² - x₂² at (5,6) - (a) Write the steps involved in writing a sample genetic algorithm.
(b) Explain the Roulette wheel analogy for the reproduction procedure in genetic algorithms. - Explain the concept of genetic programming (GP) and write the procedure for solving differential equations using GP.

(b) Explain the applications of multi objective GA problems. - A beam of rectangular cross section is subjected to a maximum bending moment of M and a maximum shear of V. The allowable bending and shearing stresses are σ and τ, respectively. The bending stress in the beam is calculated as:
σ = 6M / (bd²)
And average shear stress in the beam is calculated as:
τ = 3V / (2bd)--- Content provided by FirstRanker.com ---
Where d is the depth and b is the width of the beam. It is also desired that the depth of the beam shall not exceed twice its width. Formulate the design problem for minimum cross-sectional area using the following data:
M = 140kN m, V = 24 kN, σ = 165 MPα, τ = 50 MPa.
