Principal variation search (sometimes equated with the practically identical NegaScout) is a negamax algorithm that can be faster than alpha–beta pruning.Like alpha–beta pruning, NegaScout is a directional search algorithm for computing the minimax value of a node in a tree.
The term PVS is sometimes used to refer to any occlusion culling algorithm (since in effect, this is what all occlusion algorithms compute), although in almost all the literature, it is used to refer specifically to occlusion culling algorithms that pre-compute visible sets and associate these sets with regions in space.
In mathematics, a prehomogeneous vector space (PVS) is a finite-dimensional vector space V together with a subgroup G of the general linear group GL(V) such that G has an open dense orbit in V. The term prehomogeneous vector space was introduced by Mikio Sato in 1970.
The AN/PVS-14 Monocular Night Vision Device (MNVD) is in widespread use by the United States Armed Forces as well as NATO allies around the world. [3] It uses a third generation image intensifier tube, and is primarily manufactured by Litton Industries (Now L-3 Warrior Systems) and Elbit Systems of America (formerly Harris Night Vision, formerly Exelis, formerly ITT [4]). [5]
The AN/PVS-7 is a single tube biocular night vision device. Third-generation image intensifiers are able to be installed and are standard for military night vision. Most newer PVS-7 intensifier tubes are auto-gated to prevent image intensifier damage if exposed to intense light. The goggles have a built-in infrared Illuminator for low-light ...
The American professional wrestling promotion WWE has been broadcasting pay-per-view (PPV) events since the 1980s, when its classic "Big Four" events (Royal Rumble, WrestleMania, SummerSlam, and Survivor Series) were first established—the company's very first PPV was WrestleMania in 1985.
The Prototype Verification System (PVS) is a specification language integrated with support tools and an automated theorem prover, developed at the Computer Science Laboratory of SRI International in Menlo Park, California.
The PVS (Model Number 9000-R1) uses a clam-shell design that opens and closes using a plastic clip on the front. The two halves of the system are connected by hinges and a flexible flat cable. The top half contains the cartridge port and a polarizing layer for the LCD, which is located in each cartridge.
