- Sorting Algorithms: Techniques to arrange data in a particular order (e.g., quicksort, mergesort, bubble sort), each with different performance trade-offs.
- Searching Algorithms: Methods to find elements within data structures, such as binary search in sorted arrays or hash-based lookups.
- Data Structures: Various ways of organizing data to facilitate efficient access and modification:
- Arrays and Lists: Simple linear collections.
- Stacks and Queues: Collections with specific insertion/removal rules (LIFO and FIFO respectively).
- Trees and Graphs: Hierarchical and networked data models supporting complex relationships.
- Hash Tables: Offer fast data retrieval through key-value mapping.
Understanding these concepts enables the design of algorithms that are both correct and optimized for performance.
Key Theoretical Foundations
Theoretical computer science underpins practical computing by providing models and frameworks that define what can be computed and how efficiently:
- Automata Theory: Studies abstract machines and the problems they can solve, including finite automata, pushdown automata, and Turing machines.
- Computability Theory: Examines the limits of computation, identifying problems that are solvable by algorithms and those that are undecidable.
- Complexity Theory: Classifies problems based on the resources required to solve them, distinguishing classes such as P, NP, and NP-complete.
- Formal Languages: Investigates the syntax and semantics of languages, essential for compiler design and programming language development.
These foundations ensure a rigorous approach to designing algorithms and understanding the capabilities of computing systems.
