Classical Planning

Classical planning refers to a traditional approach in artificial intelligence (AI) where the task is to find a sequence of actions that transition from an initial state to a goal state. It is typically based on the framework of STRIPS (Stanford Research Institute Problem Solver), which is a formal language used to describe planning problems.

Classic planning problems are characterized by:

  • State Space: A set of possible configurations or states of the world.
  • Actions: A set of operators

Virtual Memory and Page Replacement Strategies

Inverted Page Tables

One entry for each real page of memory. Each entry contains the virtual address of the page stored in that real memory location, along with information about the process that owns the page. This approach decreases the memory needed to store each page table but increases the time required to search the table when a page reference occurs. A hash table is often used to limit the search to one or a few page table entries.

8085 Microprocessor: Stack Pointer, Program Counter & Interrupts

Posted by on Feb 25, 2025 in Hotel Administration and Management | 0 comments

Stack Pointer Functionality

A stack pointer is a small register that stores the address of the last program request in a stack. A stack is a specialized buffer which stores data from the top down. As new requests come in, they “push down” the older ones. The most recently entered request always resides at the top of the stack, and the program always takes requests from the top.

A stack (also called a pushdown stack) operates in a last-in/first-out (LIFO) manner. When a new data item is entered or
