algorithm - Preallocating large number of objects in C# -


this question exact duplicate of:

i implementing complex algorithm in c# uses large number of custom types.

one of main actions of algorithm creating new objects dynamically in runtime.

in order save many calls possible, aim preallocate number of different pools.

my algorithm use:

  • thousands of lists preallocated pool.
  • hundreds of structs preallocated pool.
  • hundreds of tree-like objects created in runtime, can contain large number of children.

i have read (here) c# gc optimized extremely fast allocations, know gc starts collecting when heap running low.

if algorithm make heap low gc start collecting, nothing because pools here stay, operation freeze application every time , can effect performance. should give idea of using pools , use newly allocated objects every time instead?

.net fast @ allocating objects , probs find things maybe immutable anyways. collect , if code referencing objects wont collected , pushed gen checked less often.

code profiling tools , code examples us.

this makes read

How to group boxplot outliers in gnuplot -

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
