   • Free solvers or techniques to solve nonlinear programming problems with linear OBJ and nonlinear constraints

     Top Answer

     Answered Jun 26, 2022 · 0 votes

     Here is a simple nonlinear programming problem solved with IPOPT, as suggested by @ErwinKalvelagen - there are several packages for nonlinear programming optimization, such as pyomo, gekko, and others. There is a nice discussion on High Quality Nonlinear Programming Solvers in Python. Below are a few examples in gekko that I maintain:

     Nonlinear Programming

     from gekko import GEKKO import numpy as npm = GEKKO()x = m.Array(m.Var,4,value=1,lb=1,ub=5)x1,x2,x3,x4 = x# change initial valuesx2.value = 5; x3.value = 5m.Equation(x1*x2*x3*x4>=25)m.Equation(x1**2+x2**2+x3**2+x4**2==40)m.Minimize(x1*x4*(x1+x2+x3)+x3)m.solve()print('x: ', x)print('Objective: ',m.options.OBJFCNVAL)

     With integer variables, switch to the APOPT solver (MINLP) with m.options.SOLVER=1.

     Mixed Integer Nonlinear Programming

     from gekko import GEKKOm = GEKKO() # Initialize gekkom.options.SOLVER=1 # APOPT is an MINLP solver# optional solver settings with APOPTm.solver_options = [# maximum deviation from whole number 'minlp_integer_tol 0.05', \ # covergence tolerance 'minlp_gap_tol 0.01']# Initialize variablesx1 = m.Var(value=1,lb=1,ub=5)x2 = m.Var(value=5,lb=1,ub=5)# Integer constraints for x3 and x4x3 = m.Var(value=5,lb=1,ub=5,integer=True)x4 = m.Var(value=1,lb=1,ub=5,integer=True)# Equationsm.Equation(x1*x2*x3*x4>=25)m.Equation(x1**2+x2**2+x3**2+x4**2==40)m.Minimize(x1*x4*(x1+x2+x3)+x3) # Objectivem.solve(disp=False) # Solveprint('Results')print('x1: ' + str(x1.value))print('x2: ' + str(x2.value))print('x3: ' + str(x3.value))print('x4: ' + str(x4.value))print('Objective: ' + str(m.options.objfcnval))

   • Imperative and declarative steps in Rspec

     Top Answer

     Answered Aug 19, 2010 · 8 votes

     Declarative is the way forward.

     Imperative describes the actual UI steps you have to take as a user, rather than the results you're trying to achieve. If you write your scenarios this way they'll become really brittle and impossible to maintain. Imagine if someone put a confirmation box in that imperative scenario, and there were 80 similar scenarios which also required changing.

     With declarative steps you only need to change it in the one place where the step is defined; that same declarative step is then reused for all the scenarios which need it.

   • Functional Programming Vs Declarative Programming Vs Imperative Programming

     Top Answer

     Answered Jan 26, 2021 · 134 votes

     Your example of declarative programming above is not an actual program, so it's not a good example.

     The main difference is between imperative and declarative. Functional is a particular kind of declarative.

     C, C++, Java, Javascript, BASIC, Python, Ruby, and most other programming languages are imperative. As a rule, if it has explicit loops (for, while, repeat) that change variables with explicit assignment operations at each loop, then it's imperative.

     SQL and XSLT are two well-known examples of declarative programming. Markup languages such as HTML and CSS are declarative too, although they are usually not powerful enough to describe arbitrary algorithms.

     Here is an example computation (summing the income by gender, from a suitable data source) first written in an imperative language (Javascript) and then in a declarative language (SQL).

     Imperative programming

     var income_m = 0, income_f = 0;for (var i = 0; i < income_list.length; i++) { if (income_list[i].gender == 'M') income_m += income_list[i].income; else income_f += income_list[i].income;}

     Notice:

     • explicit initialization of variables that will contain the running totals;
     • explicit loop over the data, modifying the control variable ( i) and the running totals at each iteration;
     • conditionals ( ifs) are only used to choose the code path at each iteration.

     Declarative programming

     select gender, sum(income)from income_listgroup by gender;

     Notice:

     • memory cells to contain running totals are implied by the output you declare you want;
     • any loop the CPU will need to perform (eg. over the income_list table) is implied by the output you declare you want and by the structure of the source data;
     • conditionals (eg. case in SQL) are used in a functional way to specify the output value you want based on the input values, not to choose a code path.

     Functional programming

     As I mentioned above, SQL's case is a great example of the functional way of programming, which is a restricted subset of Declarative programming in which the desired computation is specified by composing functions.

     Functions are things that accept inputs and return outputs (eg. case, sum()…)

     Composition means chaining two or more together by specifying how the output of one is fed as the input to the next (typically by writing one inside the other.) Finally the whole composition, which is still itself a big function, is applied to the available inputs to get the desired output.

     In this snippet I am declaring the output I want by composing the functions sum() and case. This is called functional programming:

     select sum(case when some_flag = 'X' then some_column else some_other_column end)from ...

     If the composition of two or more functions and their application to the input data are the only constructs available in a given language, that language is said to be purely functional. In those languages you will notice the complete absence of loops, variable assignment and other typically imperative statements.

     Edit: I recommend watching some of Anjana Vakil's talks on functional programming in Javascript, to get a better idea of what it's about.

   • Imperative vs Functional - understanding the von Neumann bottleneck

     Top Answer

     Answered Apr 16, 2018 · 1 votes

     You need to read the original paper published by John Backs "Can Programming Be liberated from the Von Neumann Style? A functional style and its algebra of programs". It basically talks about two kinds of bottlenecks one which is physical hardware limitations and the other which is a kind of conceptual bottleneck formed due to the way programmers think of languages. On your second question. As earlier languages were more closer to the respective hardware implementations the programmer thinking used to be mimic the sequential flow of events. Functional languages give us a new way to look at programs wherein parallel executions or operations on a set of data work.

     On the first question I would like to iterate a comment from wiki.c2.com

     "What does the choice of programming language have on the hardware? A functional language which is compiled to run on a von Neumann machine will still suffer the bottleneck." The answer, is ReferentialTransparency--which makes parallel computation much more tractable (and capable of being automated). Effectively parallelizing imperative languages is still an active research topic.

   Apr 25, 2024 · Imperative programming is the paradigm which is based on providing the result by focusing on the step-by-step command with manipulated state. There are many programming languages which are based on this approach of programming such as C++, python, R and Java. Control flow which exists as the major feature, facilitates the imperative programming.

   May 29, 2024 · 4. Optimization. Adding extensions and making upgrades are supported, but doing so is significantly more challenging than with declarative programming, making it harder to optimize. This owes to the step-by-step structure of the paradigm and the fact that simple tasks require more code to process.

   Imperative programming - In good old days, when programming was broadly in assembly, code would have tons of GOTOs. Even higher level languages like FORTRAN and BASIC began using the same primitives. In this programming paradigm, the entire program is a single algorithm or complete functionality written linearly - step-by-step.

8. People also ask

   What is imperative programming?

   • Imperative programming focuses on describing how a program operates step by step, rather than on high-level descriptions of its expected results. The term is often used in contrast to declarative programming, which focuses on what the program should accomplish without specifying all the details of how the program should achieve the result.
