Consider a 2d block model (and a block sequencing task for three periods using genetic algorithms. The aim is to maximize the npv for a given interest rate. F a)Suggest an encoding scheme to represent a mine plan as a chromosome. b) Using your scheme, describe how to evaluate the fitness of solution. c) Using scheme, define the chromosome of the mining sequence shown in the figure above. d)Describe possible strategies for cross over and mutation e)Define (in bullet points) the process to obtain better results starting from an initial generation. f)How can the slope constraint be ensured during cross over and mutation
