i have problem i'll explain , don't know if scheduling problem : for 30 or 31 days/month want assign doctors shifts constraints : 1-every doctor must assigned specific number of days (e.g 10 or 12) 2-everyday need specific number of doctors (e.g 3 doctors normal days , 4 tuesdays , 3 3-there's custom constraints : no 1 stay 2 continuous days or 3 in cases 4-special days holidays predefined, example doctors 1-4 must stay 2 holidays , doctors 5-8 must stay 1 holidays. 5-finally points of table predefined, example doctor 1 want stay 3th , want no shift 5th. ... i myself trying treat problem csp : a table[#doctors][#days]. each cell red green or white , doing dfs search : 1-start choosing cell assign 2-assigning red or green if valid (in stochastic order) or backtrack if not valid 3-check if solution reached o( 2^(#days*#doctors) ) without invalidity prediction now algorithm slow , don't know if faster using better function predicting invalid no...

i trying use code add xml tree simple info, have in table. each file has id need add it. corresp dictionary has file name , id couples. there empty element in xml, called idno[@type='tm'] in need enter corresponding id number. from bs4 import beautifulsoup dir = 'files/' corresp = {"00100004":"362375", "00100005":"362376", "00100006":"362377", "00100007":"362378"} filename, tm in corresp.iteritems(): soup = beautifulsoup(open(dir + filename + ".xml")) tmid = soup.find("idno", type="tm") tmid.append(tm) print soup my first problem some time works, time says tmid.append(tm) attributeerror: 'nonetype' object has no attribute 'append' i have no idea why. yesterday evening run same sample code , complains in way. i have tried etree import xml.etree.elementtree et dir = 'files/' corresp = {"00100004...

i hope shed light on me topic. if chance considered stupid question ask, i'd gladly remove question right away. i designing course timetabling system , researching, stumbled upon ga , constraint programming approaches in solving problem. however, didn't quite understand differences between 2 , advantages of 1 on other. hope explain me in layman's term or direct me site topic. thanks in advance! best regards. here's how see family of optimization algorithms: exact methods: brute force, branch , bound constraint programming (terrible name): tries reducing domain set linear programming et al: simplex, ... metaheuristics: local search: tabu search, simulated annealing, late acceptance, ... population based algorithms: genetic algorithms, swarm optimization, ... for use case course timetabling specifically, itc2007 research competition showed local search king. genetic algorithms consistently inferior , constraint programming useless due sca...

this first time using stackoverflow please patient me, heh. i'm relative newbie when comes html, css , js, gotta use them work every , then. today i've applied magnific popup site i'm working on. i'm trying use "open fade-zoom animation" example, , modify fit needs of course. popup working, indeed, div popup box isn't hiding, despite having mfp-hide class. it's weird because dreamweaver preview hide it, chrome not (i'm on latest version of chrome windows, if helps.) also, lightbox magnific popup site displays behind every popup seen. here's jsfiddle code. posting interface says need post code here here goes: here's html: <div> <a class="popup-with-zoom-anim" href="#dialog"> <span>click here display dialog</span> </a> </div> <div id="dialog" class="zoom-anim-dialog mfp-hide"> <h1>dialog title</h1> <br>...

is there way tell jquery target elements disabled? https://jsfiddle.net/o80cqp4h/ $(document).on("click", "input", function () { console.log('click'); $(this).prop('disabled', false); }); jquery ignores clicks on disabled elements (sort of), trick detect click higher chain, , find out if on input element: $(document).on("click", function (e) { $clicked = $(e.toelement); if ($clicked.is("input:disabled")) { $clicked.prop('disabled', false); } }); if have support firefox, have hackier. https://jsfiddle.net/o80cqp4h/3/ <-- firefox support https://jsfiddle.net/o80cqp4h/1/

i have list : list<string> stationnames = new list<string>() { "first station", "second station" }; and accesible pages of app if possible. how ? set on every 1 of pages, don't think efficient way. what need public static property. in 1 of classes, define such: public class myclass { public static readonly list<string> stationnames = new list<string> { "first station", "second station" }; } since static properties not associated instance, can access anywhere using: myclass.stationnames edit: added readonly modifier list because, panagiotis pointed out below, not allow list modified @ other time. however, if intended behaviour, don't include readonly modifier.

i have problem qloggingcategory(const char * category). when use like: qstring rt = "3"; qstring sv = "p"; qloggingcategory dailylogger(qstring(rt+sv+"logger").tostdstring().c_str()); it doesn't work (my custom message handler doesn't recognize category). but when use: qloggingcategory dailylogger("3plogger"); message handler sees category. here's handler function: void mymessageoutput(qtmsgtype type, const qmessagelogcontext &context, const qstring &msg) { if (qstring(context.category).contains("3")) { //some code } } why computed category name not work? qloggingcategory retains copy of char* pointer it's constructed. pointed-to characters must remain valid , constant life of qloggingcategory instance. in failing example, c_str() returns temporary no longer valid after std::string goes out of scope. qloggingcategory pointing @ invalid memory (giving un...
