optimization - MATLAB Genetic Algorithm "Subscripted assignment dimension mismatch" Error -

-

when trying use genetic algorithm solver in matlab, i'm getting following "subscripted assignment dimension mismatch" error: error message pastebin

now, says error has fitness function @ end, when test fitness function separately, works without errors. can link code fitness , constraint functions if help.

thank much!

i think see happening... because 1 of appendages cdraft inside if, don't return same length vector - i.e., return constraint vector first time, preallocates matrix constraint output, next time round give doesn't fit in matrix, error.

the clue in error stack: @ top of stack have

subscripted assignment dimension mismatch.

error in c:\program files\matlab\r2012b\toolbox\globaloptim\globaloptim\private\gaminlppenaltyfcn.p>i_convectorizer (line 135)

clearly not function you've written, , inspecting function there's nothing should cause error. end of error gives clue

caused by: failure in initial user-supplied fitness function evaluation. ga cannot continue.

the ga function reporting error in bit of code handles user-supplied constraints. whole bit of code (the call user-supplied function , other associated lines) within 1 try...catch statement returns error. this:

try     c = userconfun(x);     if isempty(chistory)         chistory = zeros(length(c), 1000); % or whatever     end     chistory(:, currentiterationindex) = c; catch err     error('failure in user-supplied fitness function blah blah blah'); end

consequently, looks error came function, though occurred after function returned.

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

How to call a javascript function after the page loads with a chrome extension? -

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey? (function submitaction() ). both chrome extensions , greasemonkey offer ways specify when script inject if executed. in chrome extension, you set in manifest : "content_scripts": [ { "run_at" : "document_idle", in greasemonkey compatible userscripts, set in metadata // @run-at document-end in both cases, have add script if want ensure resources loaded when function executed : document.addeventlistener('load', submitaction);
