Two interesting new features in Netlogo's announcement yesterday. - new experimental __includes keyword allows splitting model code into multiple files
- Mathematica-NetLogo link provides a real-time link between Mathematica and NetLogo, for controlling model runs and visualizing and analyzing results after the fact or in real time Full announcement below. -Steve The Center for Connected Learning and Computer-Based Modeling at Northwestern University is pleased to announce the release of NetLogo 4.0beta5. NetLogo 4.0beta5 is available for free download from http://ccl.northwestern.edu/netlogo/. <http://ccl.northwestern.edu/netlogo/.> This is a BETA release of NetLogo. As such, there may be a few bugs. As far as we know, this release is reliable. Nonetheless, if you want to use a NetLogo which has proved stable, please stick with NetLogo 3.1.4 for now. Please try 4.0beta5 out and send us bug reports at [EMAIL PROTECTED] <mailto:bugs%40ccl.northwestern.edu> and other suggestions and comments at [EMAIL PROTECTED] <mailto:feedback%40ccl.northwestern.edu> . If you are a Mathematica user, you might want to try out the NetLogo-Mathematica link, new in this release. We have found combining the power of ABM and symbolic scientific computing to be quite powerful. For those of you who have been inquiring about colors: In case you missed it, in beta3, NetLogo color variables can now take values from the full RGB color space. The following is a (partial) list of changes made and new features added since the previous beta, NetLogo 4.0beta3. (For a complete list of changes since 3.1.4 see http://ccl.northwestern.edu/netlogo/whatsnew4_0.html <http://ccl.northwestern.edu/netlogo/whatsnew4_0.html> .) * models: + new earth science model: Climate Change new chemistry model: Diprotic + Acid new materials science model: Solid Diffusion new mathematics + model: Surface Walking 2D new network model: Team Assembly new + unverified El Farol model replaces old El Farol which is now named El Farol Network Congestion + improved models: Conic Sections 2 (now verified), Echo (now verified), Rebellion (bugfixes; now verified), Heatbugs (improved visuals), Small Worlds (bugfix), Planarity (simpler code), Daisyworld (now verified) + new Code Examples: Ask-Concurrent Example, Ask Ordering Example, Random Network Example, Fully Connected Network Example, Mobile Aggregation Example, Wall Following Example, Circular Path Example + new HubNet activities: PANDA BEAR + new HubNet code example: Template + improved models: Planarity (simpler code), Autumn (now verified), Plant Hybridization + improved HubNet activities: Dice Stalagmite HubNet (now verified), Bug Hunters Camouflage (now verified), Root Beer Game, Disease Doctors, Minority Game * features: + new experimental __includes keyword allows splitting model code into multiple files + Mathematica-NetLogo link provides a real-time link between Mathematica and NetLogo, for controlling model runs and visualizing and analyzing results after the fact or in real time + output areas now have editable font size the tie command is no longer + experimental; new link variable tie-mode can be set to "fixed", "free", or "none" * language changes: + old rgb and hsb primitives renamed to approximate-rgb and approximate-hsb; they now expect inputs in 0-255 range instead of 0-1.0 + new primitive import-pcolors-rgb imports images into the patches as RGB colors + the file-read primitive now skips over comments code may now set a + slider to values which violate the slider's min, max, and increment + new reporter all? tests whether all agents in an agentset satisfy a condition + the hsb and rgb reporters now report RGB lists instead of NetLogo colors + added is-<link-breed>? primitive + added is-directed-link and is-undirected-link? primitives the table + extension now restricts table keys to be numbers, strings, booleans, or nested lists of same * fixes: + new monitors now default to full precision, not 3 decimal places the + file-read reporter now reads very long lists drastically faster + fixed 4.0-only bug where some list primitives such as sum and mean didn't work properly with the new of primitive in some cases + fixed 4.0-only bug where import-world didn't work with arrays and tables + fixed 4.0-only bug where importing shapes caused a Java exception + fixed 4.0-only bug where the speed slider didn't function well with continuous updates (there was a sharp discontinuity in speed on the left) + fixed 4.0-only bug where using the speed slider to fast-forward a model with tick-based updates and fractional updates could cause view updates at incorrect times + fixed 4.0-only bug where applets required additional jars besides just NetLogoLite.jar + fixed some 4.0-only bugs in plotting Please send bug reports to [EMAIL PROTECTED] <mailto:bugs%40ccl.northwestern.edu> and other suggestions and comments to [EMAIL PROTECTED] <mailto:feedback%40ccl.northwestern.edu> . We also have three mailing lists for NetLogo: - netlogo-announce: occasional release announcements only - netlogo-users: discussions about NetLogo - netlogo-educators: discussions about teaching with NetLogo http://ccl.northwestern.edu/netlogo/ <http://ccl.northwestern.edu/netlogo/> has info on all three. Credits: NetLogo was designed and authored by Uri Wilensky, project leader and director of the CCL. The lead developer is Seth Tisue. Many others have contributed greatly. HubNet was jointly designed by Uri Wilensky and Walter Stroup. The design of NetLogo was supported through funding from the National Science Foundation (grants REC 9632612, REC 9814682, REC 0126227, CCR 0326542). Additional support for the design of HubNet (calculator version) was provided by Texas Instruments.
