  FP techniques in Lisp: Data sharing | Lisp, Languages | New Artisans LLC
There are many facets to FP, but one of its core tenets is this: That all inputs to a function are immutable; that all outputs from a function must remain immutable; and that no environmental side-effects can occur in any function.
This level of complexity is avoided in C++ by carefully drawing lines between code boundaries, and safely allowing direct modification of data.
FP languages get around these two extreme by using a technique I call “maximal sharing”.

 Objective scientific proof of OOP's validity? Don't need no stinkun' proof. | Lambda the Ultimate
FP very much likes to make things on the fly, such that most, if not every FP language is garbage collected.
The point is that until FP tool authors begin to write tools that are *perceived* by the industry as being competitive with existing tools on the performance playing field, FP will remain a niche market.
Thing is, most FP languages are very concise, small languages and their expressiveness allows for saying a lot (doing a lot of work) in a few sentences, thereby not really needing a huge, bloated IDE.

 A Prospective Study of Emergency Medicine Residents' Attitudes toward Family Presence during Pediatric Procedures.
Complexity of the procedures to be performed appears to be a significant factor in residents' acceptance of FP.
When comparing the practices of EM residents regarding FP during pediatric resuscitation in the setting of a children's hospital ED vs. a general ED it seems that a greater number of families would be allowed to be present during resuscitation at a children's hospital ED.
Complexity of the procedures performed appears to be a significant factor in decreasing residents' acceptance of FP.

Since the very beginning the notion of complexity of finite objects was considered as an algorithmic counterpart to the notion of Shannon entropy.
We investigate the complexity of depth-3 threshold circuits with majority gates at the output, possibly negated AND gates at level two, and MODm gates at level one.
Especially, the complexity of k-locally self reducible sets for all numbers k, as well as the complexity of width-3 or width-4 bottleneck Turing machines are determined completely.

 warp 9.99!: A sincere comment on functional programming
FP is better because referential transparency allows functions to be tested as individual units...in FP, the result depends only on its arguments, and not in global state outside of the function.
FP is not inheritly difficult: see, for example, students who first learnt Scheme (those not previously affected by the BASIC desease).
Now, considering both performance and complexity, FP may be much easier and more efficient, but it may be exactly the opposite.

If you add a symbol to an equation, the result is more complex: X + 1 = 3 is more complex than X = 3 X + 1 = ln(3) is more complex than X + 1 = 3 X - 7 = 4^2 is more complex than X - 7 = 4.IP 2.
If two equations are the same except for one number, the equation with the higher number is more complex: X + 1 = 5 is more complex than X + 1 = 3 X^3 + 1 = 3 is more complex than X^2 + 1 = 3.IP 3.
If two equations are the same except for one symbol, the equation with the "more exotic" symbol is more complex: X ^ 5 = 3 is more complex than X + 5 = 3.P As.B ries searches it finds solutions -- these are equations for which X is close to being an exact answer.

 Products, Tools & Resources > Programming Languages Table
Many years ago, Capers Jones and SPR developed a function point (FP) estimation technique called "backfiring" wherein a table of common programming languages was produced identifying the approximate number of logical source statements (not to be confused with physical lines of code) of each language that correlated roughly with a single function point.
Of course, as even novice FP counters know, there is no such thing as a single FP.
FP values come in small groups of three, four, or more, depending on the functional type and relative complexity.

 IFPUG Bulletin Board: Simple function vs HIGH Complexity
FP failed to reflect the actual complexity of the API we built.
Since as a project manager, we have to derive the efforts (in person-days) from the FP Size, it is important that, the estimated efforts are accurate and reflect the real efforts, which software developers have to spend in building the software.
If FP SIZE does not take into account the efforts to be spend on building "Infrastructural Software"(I am using this word for software which generates system logs, audit trails, performance logs etc.), then it really becomes difficult to estimate EFFORTS from the FP SIZE.

 Dr. Dobb's | Functionally Superior | May 1, 2001
McCabe attempted to quantify complexity by analyzing the number of paths the code could follow during execution, while Halstead focused on counting operators and operands.
Much as UML appears to have "won" the debate over which analysis and design notation is superior, FP appears to have won the hearts and minds of most measurement practitioners, as I found out when I recently surveyed software engineering literature published by the ACM and IEEE.

 CK: My verdict on the Scala language
The complexity of its functional language is surprisingly high, and the complexity of the libraries are a function of both the type system and coding complexity.
Another major point of complexity in Scala is for comprehensions, which are also called sequence comprehensions (I haven’t been able to figure out which is the preferred term—did I mention the state of the documentation?).
Both Ruby and Python have some FP aspects; C# 3 has functional aspects; Microsoft has invested substantially in creating a first class development environment for F#; and Scala is generating no small amount of buzz in large part because it unifies the functional and OO worlds.

Although this approach may be simpler for a programmer, it incurs a much larger area and timing cost, by increasing busses, register file ports, execution hardware, and scheduling complexity.

The complexity of adding another set of overlapped state was overwhelming.

Because each Low table is worth 7 FPs, the FP count for these six tables would be 42 FPs (6x7=42).
Because of their DET and RET counts, all four of the groups are considered "Low" in complexity.

The pruning algorithm (which uses heap selection) has worst case complexity O(L*log(K)), where L is how large a newly computed matrix column can get before it is reduced to at most K entries\&.
L is \fIbound by\fP the smallest of the two numbers N and K^2 (the square of K), but on average L will be much smaller than that, as the presence of cluster structure aids in keeping the factor L low\&.
It is safe to say that in general the worst case complexity of mcl is of order O(N*K^2); for extremely tight and dense graphs this might become O(N*N*log(K))\&.

The weights are based on the complexity of the feature being counted.

Roughly, the analogue of #P for parameterized complexity.
In descriptive complexity, uniform AC can be characterized as the class of problems expressible by first-order predicates with addition and multiplication operators - or indeed, with ordering and multiplication, or ordering and division (see [Lee02]).
Finding a maximum flow, which is P-complete, can be done in CP Based on this the authors argue that "P is contained in CP," but this seems hard to formalize, since CP is not a complexity class in the usual sense.
