40 | | * Wojciech - the optimiser might have problems with that. |
41 | | * Non-fittable parameters |
42 | | * Involved with a constraint |
43 | | * Calculated outputs |
44 | | * See SLD profiles, see 3D shape |
45 | | * Narayan: Make sure that it is clear that constrained parameters are visible and clear that they are constrained. |
| 40 | * Wojciech - the optimiser might have problems with that if we are not careful. |
| 41 | * RKH: Would need non-fittable (static) parameters |
| 42 | * PDB: this is also been needed with constraints |
| 43 | * AJJ: Also been needed in calculated outputs |
| 44 | * "There is a ticket for that" |
| 45 | * Also other static output plots (see SLD profiles, see 3D shape) would be nice .. though off-topic here. |
| 46 | * Narayan: Make sure that all constrained parameters (fitable or not) are visible and that it is clear that they are constrained. |
54 | | * Beta |
55 | | * Locally monodisperse |
56 | | * More ways of dealing with structure factors |
57 | | *pyPRISM - will be implemented in SasView by Tyler Martin |
58 | | * Discussion of SasFit / SasView |
59 | | * Models |
60 | | * OZ Solver |
61 | | * More ways of dealing with polydispersity |
62 | | * Orientation dependent Structure factors that depend on form factor (amplitude) |
63 | | Write analytical ones |
64 | | Yun - only good for hard sphere and spherical particles |
65 | | Yun - Continuous distributions in OZ framework is hard |
66 | | Yun - should go for numerical solutions for more complex interaction potentials |
67 | | Yun - for e.g. mixture of latex and gold, need cross terms, so need complex amplitudes |

| 65 | * Probably for most cases nee to just write analytical ones |
| 66 | * Yun - Most cases will only be good for hard sphere and spherical particles |

72 | | Andrew has had student working on it. Difficult. Needs hypergeometric functions. |
73 | | MLZ have been working on it too - a few simple models. |
74 | | They have some proof of concept in Born Again |
75 | | Need to work out API to work with SasView |
76 | | Plan for this ... |
77 | | Aim for next Code Camp to have BornAgain team integrate their code. |
78 | | Check SasFit - Joachim may have implemented already. |
| 74 | * Andrew has had student working on this. It is quite difficult. Key is the use of hypergeometric functions. This might also be good for integration speeds in general (see below). |

93 | | * Wojciech : Idea is that there is a summer student at ISIS working with Anders |
94 | | Mantid have been testing their optimisers seeing how they perform on different classes of problems. Want to do something similar for SasView |
95 | | * Test SasView optimisers against their defined problems |
96 | | * Identify classes of problems that would be representative for the SANS community |
97 | | * AJJ - need to know the answer? |
98 | | * AJJ - how is SANS mathematically different from other test cases? |
99 | | * RKH - What about things where we have models that have multiple possible simulations? |
