Computer science. Correct answer will be upvoted else downvoted. scale has a strange deformity: if the absolute weight on it is by and large x, it will detonate. Would he be able to put all n gold pieces onto the scale in some request, without the scale detonating during the interaction? Provided that this is true, assist him with tracking down some conceivable request. Officially, rework the exhibit w so that for every I (1≤i≤n), ∑j=1iwj≠x. Input The input comprises of various experiments. The primary line contains an integer t (1≤t≤1000) — the number of experiments. The primary line of each experiment contains two integers n and x (1≤n≤100; 1≤x≤104) — the number of gold pieces that Phoenix has and the load to keep away from, individually. The second line of each experiment contains n space-isolated integers (1≤wi≤100) — the loads of the gold pieces. It is ensured that the loads are pairwise unmistakable. Output For each experiment, if Phoenix can't put all n…

A materials engineer wants to study the effects of two different processes for sintering copper (aprocess by which copper powder coalesces into a solid but porous copper) on two different typesof copper powders. From each type of copper powder, she randomly selects two samples andthen randomly assigns one of the two sintering processes to each sample by the flip of a coin.The response of interest measured is the porosity of the resulting copper. Explain what type ofstudy this is and why.
(a) With a suitable example, show how event calculus helps us to solve real-life Al problems. (b) Suppose, following is a PDDL action schema for flying a plane from one location to another: Action(Fly (p, from, to), PRECOND:At (p, from) A Plane (p) ^ Airport (from) ^ Airport (to) EFFECT: At (p, from) A At (p, to)) Rewrite these after proper choice of some constants to instantiate the variables, yielding a ground (variable-free) action. (c) Why hierarchical planning is important in Al?
An FSM Moore Vending machine sells chocolate bars for £1 each. System’s options: 1)entering no money 2) insert 50cents followed by another 50cents => get a chocolate bar 3) insert 50cents followed by $1 => receive change => get a chocolate bar 4) insert 50cents followed by $2 => receive change => then get a chocolate bar 5) insert $1 => get a can 6) insert $2 => receive change => then get a chocolate From the above translate these options into a state diagram, (Moore machime)
The first known correct software solution to the critical-section problem for two processes was developed by Dekker. The two processes, P0 and P1, share the following variables: boolean flag[2]; /* initially false */ int turn;The structure of process Pi (i == 0 or 1) is shown below; the other process is Pj (j == 1 or 0). Prove that the algorithm satisfies all three requirements for the critical-section problem.while (true) { flag[i] = true; while (flag[j]) {if (turn == j) { flag[i] = false; while (turn == j) ; /* do nothing */ flag[i] = true;} }/* critical section */ turn = j;flag[i] = false;/* remainder section */ }
The Harvard robotics club has organized a Robothon. n robots are placed alongthe edge of a circular area at the middle of the OAT(open air theatre). Each robot will move along arbitrary tracksinside the circle while leaving behind a heat signature along its trail. However, they have beenprogrammed not to cross their own trail or the trail of another robot, neither will they ever moveout of the circle. In case a pair of robots i and j meet at any point, they are removed from the sceneand the club will pay a reward sum of M[i, j] to the owners of these robots. Note that some robotscan keep moving infinitely without ever meeting another one. Given the reward matrix M whereM[i, j] = M[j, i], design a polynomial time algorithm that determines the maximum money theclub might potentially end up spending. For this particular problem, give a very brief justificationof the recurrence. Give pseudo-code for a dynamic program which solves the recurrence efficiently Youdo not need to prove…
