[Solved] How would I program an algorithm to solve this puzzle? [closed]

by

You can see this as a graph theory problem (http://en.wikipedia.org/wiki/Graph_theory). Each given state of your puzzle is a Vertice of the graph, and each light switching is an edge that takes the Graph to another state. Given a starting state, if you expand your graph breadth-first, your will find the sortest solution (http://en.wikipedia.org/wiki/Breadth-first_search). It is … Read more

[Solved] How to put values to R Matrix cells?

by

Do this instead (add your labels to the data object, and then use geom_tile and then geom_text) gg <- ggplot(data = cbind(melted_cormat,ids, ages), aes(x=Var1, y=Var2, fill=value)) + scale_x_discrete(labels = ids ) + scale_y_discrete(labels = ids) gg + geom_raster( aes(fill=value)) + geom_text( aes(x=Var1, y=Var2, label = ages), color=”red”, size=3) This brings the needed data into the … Read more

[Solved] General Machine Learning Algorithm, Training Set -> “Predictor” [closed]

by

Well, without the general knowledge of the problem it is almost impossible to answer your question. You basically specified the process of machine learning: Take input, study it, and generate some parameters of the model and then predict results for validation set. it is the insight you provide based on the problem itself as to … Read more

[Solved] Why would we multiply something by 10 if it’s zero

by

num is initialised to be zero only in the beginning. After each iteration, its value changes as per the condition defined. As a simplified example, you can see in the for loop, a variable is initialised to zero and then condition is provided and instructed to increment or decrement (usually) until the condition satisfies. Initialising … Read more

[Solved] How to make an array using dummy values from Struct Modal class in Swift iOS

by

You need to actually initialize syncModelRecord. Try this: let syncModelRecord = SyncModelRecord(date: String(Int64(syncTimestamp!)), shakeState: 0) dummySyncModelRecordArray.append(syncModelRecord!) Another tip maybe worth exploring, you can directly decode a date and specify the decoder’s strategy for it (in your case secondsSince1970) solved How to make an array using dummy values from Struct Modal class in Swift iOS
