i'm trying solve non-linear problem: var c; var n; minimize error: ( (6770924 - (n * c * exp(-c * 1)))^2 + (3617627 - (n * c * exp(-c * 2)))^2 + (2344172 - (n * c * exp(-c * 3)))^2 ) / 3; when execute code, have success message 0 iteration: minos 5.51: optimal solution found. 0 iterations, objective 214759264300000 non lin evals: obj = 3 grad = 2. but variables 'n' , 'c' set '0'. , using answer bad value function, since nothing subtracted constant values. if take out 'n' variable function have normal answer, 'c' minimizing function. wrong model described? thanks in advance. as mentioned in this post , minos sensitive starting point. example, using 1 starting value n gives better objective value: ampl: let n := 1; ampl: solve; minos 5.51: optimal solution found. 10 iterations, objective 24439722900 nonlin evals: obj = 34, grad = 33.

i stumbled upon unexpected behaviour when using entity framework postgresql. when query context navigation property inside clause, null , fails. if add there include method pointing navigational propery it's working this work context.garages.include("postalcode").where(f=>f.postalcode.regionid == regionid) this not (postalcode null , fails on nullreference) context.garages.where(f=>f.postalcode.regionid == regionid) i don't think had add query when using mssql. can anybdoy explain me. if want navigation properties lazy loaded , need declare them virtual : public garage { //... public virtual postalcode postalcode {get;set;} } in link find conditions must follow entities if want enable lazy loading entities , have entity framework track changes in classes changes occur. if navigation property virtual , other option think cause behavior if turn off lazy loading on context: public class yourcontext : dbcontext { public your...

i decided give gradle shot in latest project featuring graphics create using gimp. i use git project , refuse commit exportet .png -graphics in repository. instead want save gimps .xcf files in order able edit graphics later on. however android application need them .png files , there whole lot of them , trying automate build-process want gradle build .png -graphics .xcf files when executing gradle build . there plugin featuring imagemagick gradle not work produces images transparency-issues. example: this image created gradle: and how should (exportet gimp): there no hidden layers , not have opacity. build.gradle: buildscript { repositories { mavencentral() } dependencies { classpath 'com.eowise:gradle-imagemagick:0.4.0' } } task build(type: com.eowise.imagemagick.tasks.magick) { convert 'xcf/', { include '*.xcf' } 'png/' actions { -alpha('on') -background('none') inpu...

google compute engine allows daily export of project's itemized bill storage bucket (.csv or .json). in daily file can see x-number of seconds of n1-highmem-8 vm usage. there mechanism further identifying costs, such per tag or instance group, when project has many of same resource type deployed different functional operations? as example, qty:10 n1-highmem-8 vm's deployed region in project. in daily bill display x-seconds of n1-highmem-8. functionally: 2 vm's might run database 24x7 3 vm's might run batch analytics operation averaging 2-5 hrs each night 5 vm's might perform batch operation runs in sporadic 10 minute intervals through day final operation writes data specific gs buckets, other operations read/write different buckets. how might costs broken out across these 4 operations each day? the usage logs not provide 'per-tag' granularity @ time , can little tricky work usage logs here recommend. to further break down u...

i want find rout b using public transport. suppose i'm found path b(i.e. sequence stops b), how create route(i.e. go d on bus 3, take bus 15 d b)? use depth first method, create graph connecting stops transport (considering connecting length). annotate each direct connection (i.e. edge in graph of transportation map) between 2 stops bus lines serve part of connection. traverse path , select of bus lines first edge. every time, recent bus line selection not available on next edge, need change busses. might want backtracking in order find connection least stops.

in short, want prevent computers on network accessing netflix until condition met. user supposed solve few problems on program before being able watch netflix. user shouldn't able watch netflix on device until after solving problems. how can program enable or disable access netflix across entire lan? perhaps there's way remotely configure these settings on router? able change router's firmware or purchase new router if needed. all advice appreciated. what you're proposing same system many airports , coffee shops use restrict access web on networks, unless user completes task. functionally, there few commercial providers this: boingo aptilo and others via forbes article for want, combination of hardware , software achieve goals. network layout similar this network diagram , shows: client computers server provides dns resolution , hosts website a switch a modem / internet access point the process include dns server returning fake ip add...

i have following swift function: func foo(bar: string)(_ baz: string) { nslog("bar \(bar), baz: \(baz)") } let f = foo("fizz")("buzz") // won't compile, foo returns void i want pass dispatch_async , can't because can't curry both parameters without invoking function. how curry both bar , baz without calling foo ? if free change function declaration, heath's answer correct. if don't want that, need use inline closure, e.g. // pre-existing foo definition func foo(bar: string)(_ baz: string) { nslog("bar \(bar), baz: \(baz)") } let f = { foo("fizz")("buzz") } f() if problem want evaluate arguments immediately, can use capture list: let f = { [a=bar(),b=baz()] in foo(a)(b) } or when written call dispatch_async : dispatch_async(queue) { [a=bar(),b=baz()] in foo(a)(b) } this works because capture list evaluated caller when closure created (as opposed being evaluated whe...

excerpt main here: let value: value = json::from_str(&sbuf).unwrap(); let coords = value.find("coordinates").unwrap().as_array().unwrap(); let x = future::spawn(|| coords.iter().fold(0f64, |mut a,b| { += read_coord_value(&b, "x"); })); let y = future::spawn(|| coords.iter().fold(0f64, |mut a,b| { += read_coord_value(&b, "y"); })); let z = future::spawn(|| coords.iter().fold(0f64, |mut a,b| { += read_coord_value(&b, "z"); })); println!("x: {}; y: {}; z: {}", x.await().unwrap(), y.await().unwrap(), z.await().unwrap()); so, basically, i'm doing here won't work because spawn call requires passed have static lifetime--which means there no work can avoid repeating. @ all. pointless. what's good way threading here? here, multithreading, need used scoped threads, std::thread::scoped(..) . these threads not need 'static closure execute, must joined. for exampl...

i have 2 abstract grails domain classes like abstract class { static hasmany = [ b : b ] static mapping = { tableperhierarchy false } } class achild extends { } abstract class b { static belongsto = static mapping = { tableperhierarchy false } } class bchild extends b { } i have code does a = new achild() a.b << new bchild() a.save(flush:true) this works expected now, when try do b.delete(flush:true) this fails because of referential integrity violation in join table created between a/b. looks first query gorm part of delete delete b table, not join table, , join has reference b table id, causes violation. delete b id=? , version=? the reason keep a , b in domain folder can things a.list() , moving out src/groovy last option. i think bug in gorm abstract classes. have opened issue https://github.com/grails/grails-core/issues/593
