Problems that are both in NP and NP-hard
Problems that are undecidable
Problems that only have exponential-time solutions
In a deterministic finite automaton (DFA), which property holds true?
It allows multiple transitions for the same state and input
It requires exactly one transition per state and input symbol
It permits epsilon transitions
It uses a non-deterministic approach
Which algorithm is most suitable for finding the shortest path in a graph with negative edge weights, absent negative cycles?
Dijkstra's algorithm
Bellman-Ford algorithm

What is the primary advantage of greedy algorithms in solving optimization problems?
They guarantee finding the global optimum for all types of problems.
They are simple and often efficient when the problem has the greedy-choice property.
They always explore all possible solutions.
They are based on dynamic programming techniques.
For which type of problems is dynamic programming most effective?
Problems with independent subproblems
Problems that exhibit overlapping subproblems and optimal substructure
Problems that require real-time processing
Problems that are purely probabilistic
Which description accurately characterizes a Turing machine?
A model with finite memory that handles only simple computations
A theoretical model that processes symbols on an infinite tape based on a set of rules
A physical computer designed to implement complex algorithms
An automaton that only recognizes regular languages
What does the concept of undecidability imply in computation theory?
All problems can eventually be solved given enough time
Some problems have no algorithm that can decide the solution in general
Every problem can be solved using approximation algorithms
Undecidability only applies to optimization problems
Which reduction approach is commonly employed to prove that a problem is NP-complete?
Reducing the problem from an NP-hard problem to a known NP-complete problem
Reducing a known NP-complete problem to the problem in question
Reducing a polynomial time problem to an exponential time problem
Reducing a combinatorial problem to a recursive algorithm
How does recursion fundamentally differ from iteration in algorithm implementation?
Recursion uses explicit state machines while iteration requires backtracking
Recursion solves a problem by calling itself with a smaller input, whereas iteration uses loops
Recursion is always less efficient than iteration
Recursion and iteration are essentially identical in all cases
Which property is critical for applying dynamic programming to a problem?
Overlapping subproblems
Lack of a recursive structure
Multiple base cases
Non-deterministic behavior
What is the primary goal of algorithm analysis?
To determine the theoretical efficiency and resource usage of algorithms
To convert recursive algorithms into iterative ones
To design user interfaces for algorithm visualization
To classify algorithms based on their programming language
Which statement best describes the limitations of computation as discussed in complexity theory?
Every computational problem is solvable in polynomial time with optimal hardware
Some problems are inherently unsolvable or do not have efficient algorithms, regardless of hardware improvements
All problems can be solved efficiently if the dataset is small
The only limitation is the physical memory available to a computer
