The correct statements are: In complexity study, a problem is considered easy if it is solvable and hard if unsolvable. For hard or intractable problems, it is impossible to find scalable optimal solutions. Heuristic solutions are supposed to be efficient and good, though not optimal. Every optimization problem can be transformed into a verification decision problem.

A problem with optimization is specified:The input is one instance as a prerequisite.Postconditions: The result is one of the acceptable solutions in this situation, with the best (minimum or maximum, as appropriate) success metric. (The outputted solution need not be original.)
The missionaries and cannibals problem is usually stated as follows. Three mission- aries and three cannibals are on one side of a river, along with a boat that can hold one or two people. Find a way to get everyone to the other side, without ever leaving a group of mis- sionaries in one place outnumbered by the cannibals in that place. This problem is famous in AI because it was the subject of the first paper that approached problem formulation from an analytical viewpoint (Amarel, 1968). a. Formulate the problem precisely, making only those distinctions necessary to ensure a valid solution. Draw a diagram of the complete state space. b. Implement and solve the problem optimally using an appropriate search algorithm. Is it a good idea to check for repeated states? c. Why do you think people have a hard time solving this puzzle, given that the state space is so simple?
Correct answer will be upvoted else Multiple Downvoted. Computer science. Berland local ICPC challenge has quite recently finished. There were m members numbered from 1 to m, who contended on a problemset of n issues numbered from 1 to n. Presently the article is going to happen. There are two issue creators, every one of them will tell the instructional exercise to precisely k back to back errands of the problemset. The creators pick the section of k continuous errands for themselves autonomously of one another. The sections can correspond, meet or not cross by any means. The I-th member is keen on paying attention to the instructional exercise of all continuous errands from li to ri. Every member consistently decides to pay attention to just the issue creator that tells the instructional exercises to the most extreme number of assignments he is keen on. Leave this greatest number alone artificial intelligence. No member can pay attention to both of the creators, regardless of…

Please solve max 30 minutes thank u Boolean Satisfaction Problem Boolean Satisfiability Problem (SAT) (https://en.wikipedia.org/wiki/Boolean_satisfiability_problem) is one of the most important problems in Computer Science. SAT is a problem that has NP-Complete complexity, where the only way to solve the problem is to try all the possibilities and check which one is correct. [LO 1, LO 2, LO 3 & LO 4,] Briefly explain how you use Strongly Connected Component (SCC) to solve the special case of the Boolean Satisfiability Problem, namely 2-SAT (https://en.wikipedia. org/wiki/2-SAT) . This solution has linear complexity. NOTE LO1: Explain fundamental concept of analysis arithms. LO2: Apply algorithm techniques and methods. LO3: Solve a problem using specific algorithm. LO4: Compare several algorithm design methods

(Providing examples from the class lectures is allowed.)
The optimality concept in dynamic programming is explained.
