Consider the (directed) network in the attached document We could represent this network with the following Prolog statements: link(a,b). link(a,c). link(b,c). link(b,d). link(c,d). link(d,e). link(d,f). link(e,f). link(f,g). Now, given this network, we say that there is a "connection" from a node "X" to a node "y" if we can get from "X" to "Y" via a series of links, for example, in this network, there is a connection from "a" to "d", and a connection from "c" to "f", etc.
Correct answer will be upvoted else downvoted. We will consider cells of a square network n×n as contiguous in the event that they have a typical side, that is, for cell (r,c) cells (r,c−1), (r,c+1), (r−1,c) and (r+1,c) are nearby it. For a given number n, build a square lattice n×n to such an extent that: Every integer from 1 to n2 happens in this network precisely once; On the off chance that (r1,c1) and (r2,c2) are contiguous cells, the numbers written in them should not be neighboring. Input The principal line contains one integer t (1≤t≤100). Then, at that point, t experiments follow. Each experiment is characterized by one integer n (1≤n≤100). Output For each experiment, output: - 1, if the necessary network doesn't exist; the necessary lattice, in any case (any such network if a significant number of them exist).

Please answer the following question in depth with full detail. Suppose that we are given an admissible heuristic function h. Consider the following function: 1-h'(n) = h(n) if n is the initial state s. 2-h'(n) = max{h(n),h'(n')−c(n',n)} where n' is the predecessor node of n. where c(n',n) min_a c(n',a,n). Prove that h' is consistent.

Modeling the spread of a virus like COVID-19 using recursion. Let N = total population (assumed constant, disregarding deaths, births, immigration, and emigration). S n = number who are susceptible to the disease at time n (n is in weeks). I n = number who are infected (and contagious) at time n. R n = number who are recovered (and not contagiuous) at time n. The total population is divided between these three groups: N = S n + I n + R n There are several hidden assumptions here that may or may not apply to COVID-19, such as a recovered person is assumed to not be able to get the disease a second time, at least within the time window being examined. On week 0 (the start), you assume a certain small number of people have the infection (just to get things going). Everyone else is initially susceptible, and no one is recovered. There are two constants of interest: Let period = time period that it takes for an infected person to recover (recover meaning they become not infectious to…
A 2-dimensional Turing machine has an infinite 2-dimensional grid asits storage device (one cell for every address (i, j) ∈Z×Z). Instead ofL and R, there are 5 options for the head to move from (i, j): Left (to(i −1, j), Right (to (i + 1, j)), Up (to (i, j + 1)), Down (to (i, j −1)),and Stay (remain at (i, j)) .Let us assume, that our 2-dimensional TM M has an additional 1-dimensional tape where the input is located as in a 1-tape TM. The2-dimensional storage device contains a blank symbol in every cell atthe start of the computation.Show that a 2-dimensional TM is not more powerful, i.e., every lan-guage accepted by a 2-dimensional TM M is accepted by one of ourstandard 1-dimensional TMs. You don’t have to simulate directly witha 1-tape TM, as you are allowed to use what we know about k-tape(1-dimensional) TMs without proof.Describe the moves of a simulating TM M ′ in plain English. For everypossible move of M , you have to design a sequence of moves of M ′that simulates that move of…
