Final answer:
To maximize the profit of establishing electric vehicle charging stations along the Pacific Coast Highway, a dynamic programming algorithm can be designed. The sub-problems involve finding the maximum profit at each location, considering constraints such as having at least one station along the whole highway and a minimum distance between stations. The solution involves defining sub-problems, writing recurrence relations and iteratively solving them.
Step-by-step explanation:
In this problem, we need to design a dynamic programming algorithm to maximize the profit of establishing electric vehicle charging stations along the Pacific Coast Highway. Here are the steps:
a) The sub-problems to be solved can be defined as finding the maximum profit of opening charging stations at each location, considering the constraint of having at least one station along the whole highway and a minimum distance of M miles between any two stations.
b) The recurrence relation for the sub-problems can be defined as follows:
Let dp[i] represent the maximum profit at location i. We can calculate it using the following formula:
dp[i] = max(dp[j] + pk), for all j where dk - dj >= M
Base case: dp[1] = p1
c) Here is the iterative pseudocode to find the solution:
dp[1] = p1
define dp as an array of size n
for i from 2 to n:
max_profit = -inf
for j from 1 to i-1:
if dk - dj >= M:
max_profit = max(max_profit, dp[j] + pk)
dp[i] = max_profit
return dp[n]
d) The complexity of this solution is O(n^2), where n is the number of potential locations. This is because we have nested loops to iterate over the locations and check the distances between them.
