June 27, 2023 - The drawback, however, is that dynamic programming can be challenging, compared to the easier greedy algorithms. Real-world use cases for dynamic programming include: ... ADZEN is a popular advertising firm in your city that owns all n billboard locations on Main Street. The city council passed a new zoning ordinance mandating that no more than k consecutive billboards may be up at any given time. For example, if there are n = 3 billboards on Main street and k = 1, ADZEN must remove either the middle billboard, the first two billboards, the last two billboards, or the first and last billboard.
