Algorithms for these problems include the basic brute-force search ( also called " naïve " or " uninformed " search ), and a variety of heuristics that try to exploit partial knowledge about structure of the space, such as linear relaxation, constraint generation, and constraint propagation.

A modification of Grover's algorithm called quantum partial search was described by Grover and Radhakrishnan in 2004.

To describe partial search, we consider a database separated into blocks, each of size.

Obviously, the partial search problem is easier.

They proved that it is not in fact any faster than performing a single partial search.

There are many other search methods, or metaheuristics, which are designed to take advantage of various kinds of partial knowledge one may have about the solution.

At each iteration, the search takes a step s defined by solving Hs =-g for s, where s is the step, g is the gradient vector of the function's partial first derivatives with respect to the parameters, and H is an approximation to the Hessian matrix of partial second derivatives formed by repeated rank 1 updates at each iteration.

* Local repair: each CSP is calculated starting from the partial solution of the previous one and repairing the inconsistent constraints with local search.

The above expansion reduces this question to the search for a function f whose partial derivatives ∂ f / ∂ x < sup > i </ sup > are equal to n given functions f < sub > i </ sub >.

Copy and pasting is often done by inexperienced or student programmers, who find the act of writing code from scratch difficult and prefer to search for a pre-written solution or partial solution they can use as a basis for their own problem solving.

Conceptually, the partial candidates are the nodes of a tree structure, the potential search tree.

# root ( P ): return the partial candidate at the root of the search tree.

Together, the root, first, and next functions define the set of partial candidates and the potential search tree.

Instead, a chess-playing program searches a partial game tree: typically as many plies from the current position as it can search in the time available.

Once candidate DNA sequences have been determined, it is a relatively straightforward algorithmic problem to efficiently search a target genome for matches, complete or partial, and exact or inexact.

By performing a partial and random search, LURCH looks for faults in the model and reports the pathways leading to the faults.

Best-first search is a graph search which orders all partial solutions ( states ) according to some heuristic which attempts to predict how close a partial solution is to a complete solution ( goal state ).

But in beam search, only a predetermined number of best partial solutions are kept as candidates.

If the review body finds the protest justified, it orders the total or partial reimbursement of the additional search fees, and, if applicable, the protest fee, to the applicant.

Similarly, no one identifies themselves as Amur Valley Ainu, although people with partial descent can be found in Khabarovsk.

For instance, division of real numbers is a partial function, because one can't divide by zero: a / 0 is not defined for any real a.

Suppose that F is a partial function that takes one argument, a finite binary string, and possibly returns a single binary string as output.

If only partial consilience is observed, this allows for the detection of errors in methodology ; any weaknesses in one technique can be compensated for by the strengths of the others.

* A non-recursive query is one in which the DNS server provides a record for a domain for which it is authoritative itself, or it provides a partial result without querying other servers.

Occasionally a database employs storage redundancy by database objects replication ( with one or more copies ) to increase data availability ( both to improve performance of simultaneous multiple end-user accesses to a same database object, and to provide resiliency in a case of partial failure of a distributed database ).

However, visual impairment can be a broader term, including, for example, people who have partial sight in one eye, those with uncorrectable mild to moderate poor vision, or even those who wear glasses, a group that would be excluded by the word blind.

Higher-order functions enable partial application or currying, a technique in which a function is applied to its arguments one at a time, with each application returning a new function that accepts the next argument.

Given good circumstances one might be able to discern the result of some human activity such as the changing of the Netherlands ' coast or the partial drying out of the Aral Sea, but even that would not be easy.

Furthermore, each Riemannian metric is naturally associated with one particular kind of connection, the Levi-Civita connection, and this is, in fact, the connection that satisfies the equivalence principle and makes space locally Minkowskian ( that is, in suitable locally inertial coordinates, the metric is Minkowskian, and its first partial derivatives and the connection coefficients vanish ).

In a system built from separates, sometimes a failure on one component still allows partial use of the rest of the system.

Sixty-six years after opening the mine in 1897, Hoover still had a partial share in the Sons of Gwalia mines when it finally closed in 1963, just one year before the former President's death in New York City in 1964.

If one identifies C with R < sup > 2 </ sup >, then the holomorphic functions coincide with those functions of two real variables with continuous first derivatives which solve the Cauchy-Riemann equations, a set of two partial differential equations.

The first partial face transplant was performed in 2005, and the first full one in 2010.

Typically one will be a high reflector, and the other will be a partial reflector.

Of course, air is only one possible medium to use in a realization of the metre, and any partial vacuum can be used, or some inert atmosphere like helium gas, provided the appropriate corrections for refractive index are implemented.

The cave can be explored by a self-guided audio tour, and is one of the few caves in Australia offering partial disabled access.

At nearby Gauldwell Castle ( now only with one partial wall left standing ) Mary, Queen of Scots, is reputed to have spent the night.

The sketch is a partial plan for one of the radial columns of the cupola drum of Saint Peter's.

Still, one might expect that since T is a partial function from the natural numbers onto the real numbers, that therefore the real numbers are no more than countable.

Turing machines can compute functions as follows: if f is a function that takes natural numbers to natural numbers, M < sup > A </ sup > is a Turing machine with oracle A, and whenever M < sup > A </ sup > is initialized with the work tape consisting of n + 1 consecutive 1's ( and blank elsewhere ) M < sup > A </ sup > eventually halts with f ( n ) 1's on the tape, then M < sup > A </ sup > is said to compute the function f. A similar definition can be made for functions of more than one variable, or partial functions.

Conversely, from a partial order on a partition of a set S one can construct a preorder on S. There is a 1-to-1 correspondence between preorders and pairs ( partition, partial order ).

Sub-variants of preterism include one form of partial preterism which places fulfillment of some eschatological passages in the first three centuries of the current era, culminating in the fall of Rome.
