tcl r635 65backtesting python bt

Without proof, I just claim that every function of n arguments whose characteristic integer is 2^(2^n) — 1 is a tautology (or a true statement — all bits are 1). Here is a simple example of a "chat bot" — a program that listens on an IRC chatroom, and sometimes also says something, according to its programming. For instance, here's how to make an authors' index in four lines: gives us a books list of all authors matching the given glob pattern (we reuse Tcl's functionality, instead of reinventing it...). The code below also serves as usage example: } proc docstring procname {# reports a proc's args and leading comments. Here's a little debugging helper, to find out why "know" conditions don't fire: Now testing what new magic this handful of code allows us to do. Threads: 1. but my variant of the median algorithm doesn't need a conditional — for lists of odd length it just uses the central index twice, which is idempotent for "mean", even if a tad slower. The first formats a matrix (a list of lists to Tcl) with newlines and aligned columns for better display: Short again, and slightly cryptic, as is the "outer product" routine, which takes a function f and two vectors, and produces a matrix where f was applied to every pair of a x b — in APL they had special compound operators for this job, in this case "°.x": Again, lmap (the collecting foreach) figures prominently, so here it is in all its simplicity: With these parts in place, we can see that multable2 works as we want: So why write six procedures, where one did the job already? SDC is the mechanism for communicating timing constraints for FPGA synthesis tools from When two operands occur together, the "hook" pattern is implied, which might in Tcl be written as: As KBK pointed out in the Tcl chatroom, the "hook" pattern corresponds to Schönfinkel/Curry's S combinator (see Hot Curry and Combinator Engine), while "fork" is called S' there. # This filter collects its input (should be finite ;-) into a list: # $ streamlist {foo bar grill a} | sort | collect => a bar foo grill. The most important reason people chose Python is: Python's popularity and beginner friendliness has led to a wealth of tutorials and example code on the internet. This package provides access to the platform-independent Tcl scripting language and Tk GUI elements. The ART design of combining metallic casing and super narrow bezel makes this product not just a TV, but a beautiful artwork for your living room. One point that was new for me is that the distinction between operators and operands is not cast in stone. Other streams may provide a finite but very large number of elements, which would be impractical to process in one go. Dolby Audio. They are for instance the building blocks of relational databases and spreadsheets. What's missing is the capability to randomly address parts of a stream, as is possible in Scheme (and of course their claim to do without assignment, or mutable data...) Tcl lists just don't follow LISP's CAR/CDR model (though KBK demonstrated in Tcl and LISP that this structure can be emulated, also with procs), but rather C's flat *TclObject[] style. But bare-bones has its advantages too: in order to see how a clockwork works, you'd better have all parts visible :). Let us write a simple Tcl program. This result (0 or 1) is substituted for the first word of this command. Streams are interesting if they don't deliver the same result on every call, which requires them to maintain state between calls e.g. The toplevel proc takes a paired list of inputs and expected output. But the program "dd" (which just duplicates the top of stack twice) has a stack balance of +2, and hence can never pass the example test. The "main routine" is a single line that dumps all files given on the command line: Sample output, the script applied to itself: Roman numerals are an additive (and partially subtractive) system with the following letter values: Here's some Tcl routines for dealing with Roman numerals. priority queue is any of the more clever ways: A*, Greedy, ... builds up a nest of foreachs suiting the problem, quick kills (with continue) to force unique values for the variables, and. Rational numbers, a.k.a. Ah, the joys of weekend Tcl'ing... — and belatedly, Happy Birthday, John! In an RPN language, the example might look like this: which has the advantage that execution goes from left to right, but requires some stack awareness (and some swaps to set the stack right ;^), Implementing Def, I took an easy route by just creating a proc that adds an argument and leaves it to the "functional" to do the right thing (with some quoting heaven :-) }. If composite functions like 'fork' are arguments to o*, we'd better let unknown know that we want auto-expansion of first word: Also, we need a numeric sort that's good for integers as well as reals ("Def" serves for all kinds of aliases, not just combinations of functions): As this file gets tacitly sourced, I am pretty confident that I've reached my goal for this weekend — even though my median doesn't remotely look like the J version: it is as "wordy" as Tcl usually is. However, this is no fundamental problem — consider that. in state space searching, where the kind of container of the to-do list determines the strategy: Recent-use lists: A variation that can be used both in a stack or queue fashion is a list of values in order of their last use (which may come handy in an editor to display the last edited files, for instance). ", http://csc.smsu.edu/~shade/333/project.txt, https://en.wikibooks.org/w/index.php?title=Tcl_Programming/Examples&oldid=3678753. The "machine" itself takes a list of alternating labels and state code; if a state code does not end in a goto or break, the same state will be repeated as long as not left, with goto or break (implicit endless loop).
