  Problem size -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-08)
The problem size measures the size, in some sense, of the input to the algorithm.
The problem size has to be cleanly defined before an algorithm analysis can be attempted.
For many problems, the problem size is taken to be the number of (The cutting part of a drill; usually pointed and threaded and is replaceable in a brace or bitstock or drill press) bits required to encode the input.

 Problem size - Wikipedia, the free encyclopedia
For many problems, the problem size is taken to be the number of bits required to encode the input.
For instance, if the problem is to square a given integer, we would typically measure the input size as the logarithm of the input integer (since that describes how many bits are needed to encode the integer in binary notation).
However, often the encoding of the input is not canonical; if for instance the problem is one in graph theory, then different problem sizes can be defined, since a graph can be encoded as a list of edges or alternatively as an adjacency matrix.

 Ex Astris Scientia - Starship Class Inconsistencies
It is not really a problem, but worth the question why the design of the Miranda as a new class has taken the same direction as that of the Constitution refit, although the conditions should have been considerably different.
The only remaining problem is that the Enterprise-A was retired before her time.
Owing to the rather small size of the model, the additional parts were taken from an AMT model.

Rather it is a function of 1) the nature of the problem being solved, 2) the design of the algorithm and 3) the "size" of the problem.
The size of a problem is important in measuring performance.
Size is typically measured in terms of number of objects in the problem (number of elements in a list,an array, etc)

 HPL Frequently Asked Questions
The amount of memory used by HPL is essentially the size of the coefficient matrix.
If the problem size you pick is too large, swapping will occur, and the performance will drop.
For small problem sizes however, the overhead due to message-passing, local indexing and so on can be significant.

 Variation with Problem Size   (Site not responding. Last check: 2007-10-08)
Unfortunately, a paradoxical situation can arise with some programs where as the problem size increases the amount of parallelism extracted goes down.
The problem with matrix multiply is that the sequential inner loop where the sums are being accumulated gets longer as the size of the problem is increased.
The result is that the number of frames required for the inner loop grows and reduces the parallelism available between the loops.

 Standard Excel Solver - Dealing with Problem Size Limits - Continued
If you have a linear problem -- and you've checked the Assume Linear Model box in the Solver Options dialog -- there is no limit on the number of constraints.
For nonlinear problems, you can place constraints on up to 100 cells which are not decision variables.
The Premium Solver has a limit of 250 constraints for nonlinear problems (apart from bounds on the variables and integer constraints) -- and it solves problems of this size in much less time.

 Clip Board Size - Lockergnome's Problem Solvers
Is there a setting or tweek to adjust the size of the clip board in memory.
This problem occurs when the Office Clipboard is enabled and you copy an item that would cause the Office Clipboard to exceed four megabytes (MB) of random access memory (RAM).
So I figure it must be a pre set size issue for the clip board.

 Non-Symmetric Problem
Figure 5 shows what happens to scalability when the total problem size is fixed and the number of processors is varied using PETSc on IA32.
Figure 6 shows a cross-platform comparison between the IA32 cluster and the Origin2000 with fixed total problem size scaling.
On the other hand, the MatSolve portion of the solve generally decreases as the number of processors grows due to the almost embarassingly parallel nature of the solves on the individual blocks of the block Jacobi preconditioner.

 Welcome to the Post's Correspondence Problem!
Post's correspondence problem was first raised by Post in 1946 as undecidable problem [1].
It is frequently used in the literature as a basis to prove the undecidabily of other problems.

 Standard Excel Solver - Dealing with Problem Size Limits
Before you reach the standard Solver's size limits, you may find that the solution process takes a long time.
The only way around this limit is to change your model so that some of the cells you have chosen as decision variables are removed from the By Changing Cells reference, and are held constant in the optimization process.
Frontline's Premium Solver has a limit of 1,000 decision variables for linear problems, and 500 variables for nonlinear problems -- and it solves problems of this size in much less time.

 Suicide: A Worldwide Problem: Size & Trends
Relative to how large a problem it is, suicidal behavior and its prevention receive very little funding support from governments or public health authorities around the world.
This is how we can compare the rates between Australia, Canada, Norway and the United States with their different population sizes or between different age groups with their different suicide numbers and population sizes.
The problem of suicide in the elderly has not changed, but it has been overwhelmed in recent years by the increase in suicide among younger people.

 Reasoning Errors In The Current Models of Human Cognition
The main problem is that currently we only know about the existence of connections between various brain structures, but we don't have a clue about their activity in various situations.
For example, even though the size of Brodmann's area 17 (now called V1) can vary from one individual to the next by 2- to 3-fold (3, 5), area 17 (V1) is always next to area 18 (V2) and never has area 19 (V3) as a nearest neighbor.
In its outcome, this error is equivalent to the model space size error, but it stems from different source: in the model space size error the researcher knows that the feature is complex, but is unaware of the model space size problem, while here the researcher is unaware of the complexity of the feature.

 The cutting sticks problem
The problem is special case of the knapsack problem, which is stated as: given a number of bags with given size, can a number of objects be fitted into the bags.
I should notice that this problem admits a much more compact encoding, with only the parameter "n" being specified in log(n) bits, since we are implicitly quantifying over all the appropriate partitions of n(n+1)/2.
The problem then becomes one of shuffling the rods around so that a rod of length 1 and a rod of length k-1 appear on the same stick.

 Varying Diameter and Problem Size   (Site not responding. Last check: 2007-10-08)
For image processing and graph theoretic algorithms we analyze the time as a function of the mesh diameter and problem size.
We show that for many problems, smaller diameters can yield faster algorithms, and that there is a choice of diameter that is simultaneously best for several of these problems.
Further, for these problems and this number of processing elements (or any smaller number), the mesh is an optimal interconnection scheme.

 Problem with size of structers
If you're going to try to use 'C' structures to map language types onto the communications frame/packet format, you are going to have to study the manuals for both platforms very carefully - playing particular attention to data sizes, endianness, packing, alignments, and all the other implementation-specific details.
ANSI also says that bitfields are always part of an 'int', so there's a potential portability issue for bitfields in other sizes like bytes.
Most embedded compilers will let you specify other sizes for bitfields, but it's non-standard behavior.
