Suppose that the minimum number of buses required during the ith hour of the day be denoted by bi (i=1,…,24). Each bus works for 6 consecutive hours. If the number of buses during the ith hour is more than bi, then a cost (Ci) incurs per hour per bus. Formulate the problem as a linear programming problem to minimize the total cost of extra buses.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
