networking - Is Backpropagation okay for this or should i try another approach? -


i'm making kind of "the life game" creatures , food on world. creatures eat food in order gain energy , when have enough energy reproduce. energy food provides based on time food has been on world, longer better. i'm using genetic algorithm creatures want them learn what's best through generations because thing have 4 ways search food:

1.- nearest one

2.- 1 provides more energy

3.- 1 provides best % mutate genes , gain cool new things

4.- 1 represents lower danger reach

i have neural network input of 100 genes, 4 hidden layers , 1 output layer it's vector 4 components, each of them indicating search option should go based on genes.

network doing great initial input, thing want keep feeding network on generations can things example creatures lazy genes evolved searching nearest food 1 provides more energy can "do nothing" longer periods of time (because yea, they're lazy).

seems have pass in inputs everytime train it, impossible because new inputs generate on generations , can't training around 100 inputs every generation due high cpu ussage.

my question: propagation okay particular case or should use different approach need?

thanks in advance

edit: neural network takes around 20-60 seconds converge , every crossover might occur once every 0.2 - 2 seconds. first implementation.

javascript - Using jquery append to add option values into a select element not working -

i'm looking dynamically populate select element names of items stored array. for reason it's not working , i'm not sure why. html: <div class="col-md-4 col-md-offset-4"> <select class="select1"> </select> , <select class="select2"> </select> </div> note i'm using bootstrap layout. here's jquery i'm using try , populate ".select1" jquery: select: function() { $.each(state.greens, function(index, value) { $(".select1").append("<option value =' " + index + " '>" + state.greens[index].name + "</option>"); }); } note function 'select' stored within object called 'display'. state.greens name of array i'm trying access. so @ end of html page call display.select(); call function. no error messages showing in console. also, saw question: appending

Android soft keyboard reverts to default keyboard on orientation change -

i'm building android soft keyboard , can't seem fix bug - have arabic , qwerty keyboard , when rotate device on qwerty keyboard (or arabic shift), it's if program has "restarted" , becomes arabic keyboard without shift. the onsaveinstancestate(bundle savedinstancestate) not work because application not extend activity inputmethodservice . i put following in android manifest android:configchanges="keyboard|keyboardhidden|orientation" android:windowsoftinputmode="stateunchanged|adjustresize"> i tried using @override public void onconfigurationchanged(configuration newconfig) { super.onconfigurationchanged(newconfig); log.i(mydebug, "config changed " + currentkeyboard.equals(qwerty)); } however, currentkeyboard.equals(qwerty)) results false , made sure true before orientation change. any appreciated. i think applications fault. if application restarting on orientation change

Rendering JButton to get the JCheckBox behavior in a JTable by using images does not update my table -

i rendering jbutton image on simulate jcheckbox behavior. why don't let jtable render jcheckbox? because need bigger checkboxes , there's no way can resize them (as far know). so, have own table cell renderer , editor. both renders jbutton , checkbox images on them. trying change image checked image unchecked image (or vice versa) , update cell value (boolean true or false). however, reason, getcelleditorvalue() not update table. so, release mouse, value goes original one. any appreciated! lot! public class tableexample extends jframe { jscrollpane pane; jpanel panel; jtable table; object[][] data; mytablemodel tm; renderer buttoncolumn; public tableexample(object[][] data) throws ioexception { string[] columns = {"column#1", "column#2", "column#3", "column#4", "column#5", "column#6"}; this.data = data; this.setpreferredsize(new dimension(700, 500));
