Please provide code in Prolog.

Thanks!

3.1 Finding a path Consider the plan of a house as shown in Fig. 1. Write a Prolog description of this plan hat allows a Prolog program search for paths between locations indicated on the plan. For example, if one is Outside and wishes to find a path to the WC, then a possible answer can be: Outside Porch 1 Kitchen Leaving Room Corridor WC. Your program should Figure 1: Top view of a two bedroom house showing how different locations in and out of the house are connected. avoid loops and be as general as possible, in that, given any two locations representing an origin O and a destination D, it returns: - a path P from O to D, if it exists; - every possible path P from O to D, if there are more than one; - meaningful error messages, if the wrong input is provided for O and D. Comment the code submitted for this part to contain the name of the search algorithm that you selected to find the path. [40\%] 3.3 Paths with Costs Rewrite the problem description for the program you defined in section 3.1, to include the individual cost C (an integer describing the distance in meters) between locations of the house as shown in Fig. 2. Once you have a new representation that takes individual cost between locations into account, rewrite also you search program to calculate the total cost of a path, so that when you return a path P as a solution, you also return Ctotal. Your new program should also return every path, if there is more than one, returning the cheap ones first, and then the more expensive ones, in rank order. Then use your new program to define how to meet up from two origins 01 and 02 to a destination D (as in 3.2), only if the cost Ctotal is the same from both O1 and O2 respectively. Figure 2: Cost between locations. Test your program using Fig. 1 by asking different queries and see whether your work produces the expected outcomes. [30\%]
